Why GAO Did This Study: 

Earlier this month, United Air Lines (United) and Continental Airlines 
(Continental) announced plans to merge the two airlines and signed a 
merger agreement. This follows the acquisition of Northwest Airlines 
by Delta Air Lines (Delta) in 2008, which propelled Delta to become 
the largest airline in the United States. This latest merger, if not 
challenged by the Department of Justice (DOJ), would surpass Delta’s 
merger in scope to create the largest passenger airline in terms of 
capacity in the United States. The passenger airline industry has 
struggled financially over the last decade, and these two airlines 
believe a merger will strengthen them. However, as with any proposed 
merger of this magnitude, this one will be carefully examined by DOJ 
to determine if its potential benefits for consumers outweigh the 
potential negative effects. 

At the Committee’s request, GAO is providing a statement for the 
record that describes (1) an overview of the factors that are driving 
mergers in the industry, (2) the role of federal authorities in 
reviewing merger proposals, and (3) key issues associated with the 
proposed merger of United and Continental. To address these 
objectives, GAO drew from previous reports on the potential effects of 
the proposed merger between Delta and Northwest and the financial 
condition of the airline industry, and analyzed Department of 
Transportation (DOT) airline operating and financial data. 

What GAO Found: 

As GAO has previously reported, airlines seek to merge with or acquire 
other airlines to increase their profitability and financial 
sustainability, but must weigh these potential benefits against 
operational costs and challenges. The principal benefits airlines 
consider are cost reductions—by combining complementary assets, 
eliminating duplicate activities, and reducing capacity—and increased 
revenues from higher fares in existing markets and increased demand 
for more seamless travel to more destinations. Balanced against these 
potential benefits are operational costs of integrating workforces, 
aircraft fleets, and systems. 

DOJ’s antitrust review is a critical step in the airline merger and 
acquisition process. DOJ uses an integrated analytical framework set 
forth in the Horizontal Merger Guidelines to determine whether the 
merger poses any antitrust concerns. Under that process, DOJ assesses 
the extent of likely anticompetitive effects of reducing competition 
in the relevant markets—in this case, between cities or airports. DOJ 
further considers the likelihood that airlines entering these markets 
would counteract any anticompetitive effects. It also considers any 
efficiencies that a merger or acquisition could bring—for example, 
consumer benefits from an expanded route network. Finally, it examines 
whether one of the airlines proposing to merge would fail and its 
assets exit the market in the absence of a merger. 

One of the most important issues in this merger will be its effect on 
competition in the airline industry. For example, GAO’s analysis of 
2009 ticket data showed that combining these airlines would result in 
a loss of one effective competitor (defined as having at least 5 
percent of total traffic between airports) in 1,135 markets (called 
airport pairs) affecting almost 35 million passengers while creating a 
new effective competitor in 173 airport pairs affecting almost 9.5 
million passengers (figure). However, in all but 10 of these airports 
pairs there is at least one other competitor.

Mr. Chairman and Members of the Committee: 

We appreciate the opportunity to provide a statement for the record on 
the potential implications of the merger proposal recently announced 
by United Air Lines (United) and Continental Airlines (Continental). 
Earlier this month, these two airlines announced plans for United to 
merge with Continental through a stock swap the airlines valued at $8 
billion. This follows the acquisition of Northwest Airlines 
(Northwest) by Delta Air Lines (Delta) in 2008, which propelled Delta 
to become the largest airline in the United States. The United-
Continental merger, if not challenged by the Department of Justice 
(DOJ), would surpass Delta's in scope to create the largest passenger 
airline in terms of capacity in the United States. However, as with 
any proposed merger of this magnitude, this one will be carefully 
examined by DOJ to determine if its potential benefits for consumers 
outweigh the potential negative effects. 

Extensive research and the experience of millions of Americans 
underscore the benefits that have flowed to most consumers from the 
1978 deregulation of the airline industry, including dramatic 
reductions in fares and expansion of service. These benefits are 
largely attributable to increased competition from the entry of new 
airlines into the industry and established airlines into new markets. 
At the same time, however, airline deregulation has not benefited 
everyone; some communities--especially smaller communities--have 
suffered from relatively high airfares and a loss of service. We have 
been analyzing aviation competition issues since the enactment of the 
Airline Deregulation Act of 1978.[Footnote 1] Our work over the last 
decade has focused on the challenges to competition and industry 
performance, including the financial health of the airline industry, 
the growth of low-cost airlines, changing business models of airlines, 
and prior mergers.[Footnote 2] In the airline context, DOJ has the 
primary responsibility to evaluate most mergers in order to carry out 
its antitrust responsibilities.[Footnote 3] In its review, DOJ 
considers a number of factors, including increases in market 
concentration; potential adverse effects on competition; the 
likelihood of new entry in affected markets and possible counteraction 
of anticompetitive effects that the merger may have posed; verified 
"merger specific" efficiencies or other competitive benefits; and 
whether, absent the merger, one of the airlines is likely to fail and 
its assets exit the market. 

This statement presents (1) an overview of the factors that are 
driving mergers in the airline industry, (2) the role of federal 
authorities in reviewing merger proposals, and (3) key issues 
associated with the proposed merger of United and Continental. This 
statement is based on two previously issued reports--our 2008 report 
for this Committee on airline mergers and our 2009 report on the 
financial condition of the airline industry and the various effects of 
the industry's contraction on passengers and communities[Footnote 4]--
as well as our other past work on aviation issues. In addition, we 
conducted some analysis of the proposed United and Continental merger, 
including analysis of the airlines' financial, labor, fleet, and 
market conditions. 

To identify the factors that help drive mergers in the airline 
industry, we relied on information developed for our 2008 and 2009 
reports on the airline industry, updated as necessary. To describe the 
role of federal authorities, in particular DOJ and the Department of 
Transportation (DOT), in reviewing airline merger proposals we relied 
on information developed for our 2008 report, also updated as 
necessary.[Footnote 5] To identify the key issues associated with the 
proposed merger of United and Continental, we reviewed airline merger 
documents and financial analyst reports and analyzed data submitted by 
the airlines to DOT (Bureau of Transportation Statistics financial 
Form 41, origin and destination ticket, and operations data). We also 
analyzed airline schedule data. We assessed the reliability of these 
data by (1) performing electronic testing of required data elements, 
(2) reviewing existing information about the data and the system that 
produced them, and (3) interviewing agency officials knowledgeable 
about the data. We determined that the data were sufficiently reliable 
for the purposes of this report. We conducted this audit work in May 
2010 in accordance with generally accepted government auditing 
standards. Those standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives. 

Background: 

On May 3, 2010, United and Continental announced an agreement to merge 
the two airlines. The new airline would retain the United name and 
headquarters in Chicago while the current Continental Chief Executive 
Officer would keep that title with the new airline. The proposed 
merger will be financed exclusively through an all-stock transaction 
with a combined equity value of $8 billion split roughly with 55 
percent ownership to United shareholders and 45 percent to Continental 
shareholders. The airlines have not announced specific plans for 
changes in their networks or operations that would occur if the 
proposed merger is not challenged by DOJ. 

The airline industry has experienced considerable merger and 
acquisition activity since its early years, especially immediately 
following deregulation in 1978 (fig. 1 provides a timeline of mergers 
and acquisitions for the seven largest surviving airlines). A flurry 
of mergers and acquisitions during the 1980s, when Delta Air Lines and 
Western Airlines merged, United Airlines acquired Pan Am's Pacific 
routes, Northwest acquired Republic Airlines, and American Airlines 
and Air California merged. In 1988, merger and acquisition review 
authority was transferred from the Department of Transportation (DOT) 
to DOJ. Since 1998, despite tumultuous financial periods, fewer 
mergers and acquisitions have occurred. In 2001, American Airlines 
acquired the bankrupt airline TWA, in 2005 America West acquired US 
Airways while the latter was in bankruptcy, and, in October 2008, 
Delta acquired Northwest. Certain other attempts at merging in the 
last decade failed because of opposition from DOJ or from employees 
and creditors. For example, in 2000, an agreement was reached that 
allowed Northwest to acquire a 50 percent stake in Continental (with 
limited voting power) to resolve the antitrust suit brought by DOJ 
against Northwest's proposed acquisition of a controlling interest in 
Continental.[Footnote 6] A proposed merger of United Airlines and US 
Airways in 2000 also resulted in opposition from DOJ, which found 
that, in its view, the merger would violate antitrust laws by reducing 
competition, increasing air fares, and harming consumers on airline 
routes throughout the United States. Although DOJ expressed its intent 
to sue to block the transaction, the parties abandoned the transaction 
before a suit was filed. More recently, the 2006 proposed merger of US 
Airways and Delta fell apart because of opposition from Delta's pilots 
and some of its creditors, as well as its senior management.

Since deregulation in 1978, the financial stability of the airline 
industry has become a considerable concern for the federal government 
owing, in part, to the level of financial assistance it has provided 
to the industry by assuming terminated pension plans and other forms 
of assistance. Between 1978 and 2008, there have been over 160 airline 
bankruptcies. While most of these bankruptcies affected small airlines 
that were eventually liquidated, 4 of the more recent bankruptcies 
(Delta, Northwest, United, and US Airways) are among the largest 
corporate bankruptcies ever, excluding financial services firms. 
During these bankruptcies, United and US Airways terminated their 
pension plans and $9.7 billion in claims was shifted to the Pension 
Benefit Guarantee Corporation (PGBC).[Footnote 7] Furthermore, to 
respond to the shock to the industry from the September 11, 2001, 
terrorist attacks, the federal government provided airlines with $7.4 
billion in direct assistance and authorized $1.6 billion (of $10 
billion available) in loan guarantees to six airlines.[Footnote 8] 

Although the airline industry has experienced numerous mergers and 
bankruptcies since deregulation, growth of existing airlines and the 
entry of new airlines have contributed to a steady increase in 
capacity, as measured by available seat miles. Previously, we reported 
that although one airline may reduce capacity or leave the market, 
capacity returns relatively quickly.[Footnote 9] Likewise, while past 
mergers and acquisitions have, at least in part, sought to reduce 
capacity, any resulting declines in industry capacity have been short- 
lived, as existing airlines have expanded or new airlines have 
expanded. Capacity growth has slowed or declined just before and 
during recessions, but not as a result of large airline liquidations. 

Airline Mergers Are Driven by Financial and Competitive Pressures, but 
Challenges Exist: 

Volatile earnings and structural changes in the industry have spurred 
some airlines to explore mergers as a way to increase their 
profitability and financial viability. Over the last decade, the U.S. 
passenger airline industry has incurred more than $15 billion in 
operating losses. Several major airlines went through bankruptcy to 
reduce their costs and restructure their operations, while others 
ceased to operate or were acquired. Most recently, U.S. airlines 
responded to volatile fuel prices and then a weakening economy by 
cutting their capacity, reducing their fleets and workforces, and 
instituting new fees, but even with these actions, the airlines 
experienced over $5 billion in operating losses in 2008 before posting 
an operating profit of about $1 billion in 2009.[Footnote 10] 
Furthermore, over the last decade, airfares have generally declined 
(in real terms), owing largely to the increased presence of low-cost 
airlines, such as Southwest Airlines, in more markets and the 
shrinking dominance of a single airline in many markets. 

One of the primary financial benefits that airlines consider when 
merging with another airline is the cost reduction that may result 
from combining complementary assets, eliminating duplicative 
activities, and reducing capacity. A merger or acquisition could 
enable the combined airline to reduce or eliminate duplicative 
operating costs, such as duplicative service, labor, and operations 
costs--including inefficient (or redundant) hubs or routes--or to 
achieve operational efficiencies by integrating computer systems and 
similar airline fleets. Other cost savings may stem from facility 
consolidation, procurement savings, and working capital and balance 
sheet restructuring, such as renegotiating aircraft leases. Airlines 
may also pursue mergers or acquisitions to more efficiently manage 
capacity--both to reduce operating costs and to generate revenue--in 
their networks. Given recent economic pressures, particularly 
increased fuel costs, the opportunity to lower costs by reducing 
redundant capacity may be especially appealing to airlines seeking to 
merge. Experts have said that industry mergers and acquisitions could 
lay the foundation for more rational capacity reductions in highly 
competitive domestic markets and could help mitigate the significant 
impact that economic cycles have historically had on airline cash flow. 

The other primary financial benefit that airlines consider with 
mergers and acquisitions is the potential for increased revenues 
through additional demand, which may be achieved by more seamless 
travel to more destinations and increased market share and higher 
fares on some routes. 

* Increased demand from an expanded network: An airline may seek to 
merge with or acquire an airline as a way to generate greater revenues 
from an expanded network, which serves more city-pair markets and 
better serves passengers. Mergers and acquisitions may generate 
additional demand by providing consumers more domestic and 
international city-pair destinations. Airlines with expansive domestic 
and international networks and frequent flier benefits particularly 
appeal to business traffic, especially corporate accounts. Results 
from a recent Business Traveler Coalition (BTC) survey indicate that 
about 53 percent of the respondents were likely to choose a particular 
airline based on the extent of its route network.[Footnote 11] 
Therefore, airlines may use a merger or acquisition to enhance their 
networks and gain complementary routes, potentially giving the 
combined airline a stronger platform from which to compete in highly 
profitable markets. 

* Increased market share and higher fares on some routes: Capacity 
reductions in certain markets after a merger could also serve to 
generate additional revenue through increased fares on some routes. 
Some studies of airline mergers and acquisitions during the 1980s 
showed that prices were higher on some routes from the airline's hubs 
soon after the combination was completed.[Footnote 12] Several studies 
have also shown that increased airline dominance at an airport results 
in increased fare premiums, in part because of competitive barriers to 
entry.[Footnote 13] At the same time, though, even if the combined 
airline is able to increase prices in some markets, the increase may 
be transitory if other airlines enter the markets with sufficient 
presence to counteract the price increase. In an empirical study of 
airline mergers and acquisitions up to 1992, Winston and Morrison 
suggest that being able to raise prices or stifle competition does not 
play a large role in airlines' merger and acquisition decisions. 
[Footnote 14] 

Cost reductions and the opportunity to obtain increased revenue could 
bolster a merged airline's financial condition, enabling the airline 
to better compete in a highly competitive international environment. 
Many industry experts believe that the United States will need larger, 
more economically stable airlines to be able to compete with the 
merging and larger foreign airlines that are emerging in the global 
economy. The airline industry is becoming increasingly global; for 
example, the Open Skies agreement between the United States and the 
European Union became effective in March 2008.[Footnote 15] 

Despite these benefits, there are several potential barriers to 
successfully consummating a merger. The most significant operational 
challenges involve the integration of workforces, aircraft fleets, and 
information technology systems and processes, which can be difficult, 
disruptive, and costly as the airlines integrate.[Footnote 16] 

* Workforce integration: Workforce integration is often particularly 
challenging and expensive and involves negotiation of new labor 
contracts. Labor groups--including pilots, flight attendants, and 
mechanics--may be able to demand concessions from the merging airlines 
during these negotiations, several experts explained, because labor 
support would likely be required for a merger or acquisition to be 
successful. Some experts also note that labor has often opposed 
mergers, fearing employment or salary reductions. Obtaining agreement 
from each airline's pilots' union on an integrated pilot seniority 
list--which determines pilots' salaries, as well as what equipment 
they can fly--may be particularly difficult. According to some 
experts, as a result of these labor integration issues and the 
challenges of merging two work cultures, airline mergers have 
generally been unsuccessful. For example, although the 2005 America 
West-US Airways merger has been termed a successful merger by many 
industry observers, labor disagreements over employee seniority, and 
especially pilot seniority, are not fully resolved. More recently, 
labor integration issues derailed merger talks--albeit temporarily--
between Northwest and Delta in early 2008, when the airlines' labor 
unions were unable to agree on pilot seniority list integration. 
Furthermore, the existence of distinct corporate cultures can 
influence whether two firms will be able to merge their operations 
successfully. For example, merger discussions between United and US 
Airways broke down in 1995 because the employee-owners of United 
feared that the airlines' corporate cultures would clash. 

* Fleet integration: The integration of two disparate aircraft fleets 
may also be costly. Combining two fleets may increase costs associated 
with pilot training, maintenance, and spare parts. These costs may, 
however, be reduced after the merger by phasing out certain types of 
aircraft from the fleet mix. Pioneered by Southwest Airlines and 
copied by other low-cost airlines, simplified fleets have enabled 
airlines to lower costs by streamlining maintenance operations and 
reducing training times. If an airline can establish a simplified 
fleet, or "fleet commonality"--particularly by achieving an efficient 
scale in a particular aircraft--then many of the cost efficiencies of 
a merger or acquisition may be set in motion by facilitating pilot 
training, crew scheduling, maintenance integration, and inventory 
rationalization. 

* Information technology integration: Finally, integrating information 
technology processes and systems can also be problematic and time- 
consuming after a merger. For example, officials at US Airways told us 
that while some cost reductions were achieved within 3 to 6 months of 
its merger with America West, the integration of information 
technology processes took nearly 2 ˝ years. Systems integration issues 
are increasingly daunting as airlines attempt to integrate a complex 
mix of modern in-house systems, dated mainframe systems, and 
outsourced information technology. The US Airways-America West merger 
highlighted the potential challenges associated with combining 
reservation systems, as there were initial integration problems. 

The Department of Justice's Antitrust Review Is a Critical Step in the 
Airline Merger and Acquisition Process: 

DOJ's review of airline mergers and acquisitions is a key step for 
airlines hoping to consummate a merger. For airlines, as with other 
industries, DOJ uses an analytical framework set forth in the 
Horizontal Merger Guidelines (the Guidelines) to evaluate merger 
proposals. Footnote 17] In addition, DOT plays an advisory role for 
DOJ and, if the combination is consummated, may conduct financial and 
safety reviews of the combined entity under its regulatory authority. 

Most proposed airline mergers or acquisitions must be reviewed by DOJ 
as required by the Hart-Scott-Rodino Act. In particular, under the 
act, an acquisition of voting securities or assets above a set 
monetary amount must be reported to DOJ (or the Federal Trade 
Commission (FTC) for certain industries) so the department can 
determine whether the merger or acquisition poses any antitrust 
concerns.[Footnote 18] To analyze whether a proposed merger or 
acquisition raises antitrust concerns--whether the proposal will 
create or enhance market power or facilitate its exercise[Footnote 
19]--DOJ follows an integrated five-part analytical process set forth 
in the Guidelines.[Footnote 20] First, DOJ defines the relevant 
product and geographic markets in which the companies operate and 
determines whether the merger is likely to significantly increase 
concentration in those markets. Second, DOJ examines potential adverse 
competitive effects of the merger, such as whether the merged entity 
will be able to charge higher prices or restrict output for the 
product or service it sells. Third, DOJ considers whether other 
competitors are likely to enter the affected markets and whether they 
would counteract any potential anticompetitive effects that the merger 
might have posed. Fourth, DOJ examines the verified "merger specific" 
efficiencies or other competitive benefits that may be generated by 
the merger and that cannot be obtained through any other means. Fifth, 
DOJ considers whether, absent the merger or acquisition, one of the 
firms is likely to fail, causing its assets to exit the market. The 
commentary to the Guidelines makes clear that DOJ does not apply the 
Guidelines as a step-by-step progression, but rather as an integrated 
approach in deciding whether the proposed merger or acquisition would 
create antitrust concerns. 

In deciding whether the proposed merger is likely anticompetitive DOJ 
considers the particular circumstances of the merger as it relates to 
the Guidelines' five-part inquiry. The greater the potential 
anticompetitive effects, the greater must be the offsetting verifiable 
efficiencies for DOJ to clear a merger. However, according to the 
Guidelines, efficiencies almost never justify a merger if it would 
create a monopoly or near monopoly. If DOJ concludes that a merged 
airline threatens to deprive consumers of the benefits of competitive 
air service, then it will seek injunctive relief in a court proceeding 
to block the merger from being consummated. In some cases, the parties 
may agree to modify the proposal to address anticompetitive concerns 
identified by DOJ--for example, selling airport assets or giving up 
slots at congested airports--in which case DOJ ordinarily files a 
complaint with the court along with a consent decree that embodies the 
agreed-upon changes. 

DOT conducts its own analyses of airline mergers and acquisitions. 
While DOJ is responsible for upholding antitrust laws, DOT conducts 
its own competitive analysis and provide it to DOJ in an advisory 
capacity. DOT reviews the merits of any airline merger or acquisition 
and submits its views and relevant information in its possession to 
DOJ. DOT also provides some essential data that DOJ uses in its 
review. In addition, presuming the merger moves forward after DOJ 
review, DOT can undertake several other reviews if the situation 
warrants. Before commencing operations, any new, acquired, or merged 
airlines must obtain separate authorizations from DOT--"economic" 
authority from the Office of the Secretary and "safety" authority from 
the Federal Aviation Administration (FAA). The Office of the Secretary 
is responsible for deciding whether applicants are fit, willing, and 
able to perform the service or provide transportation. To make this 
decision, the Secretary assesses whether the applicants have the 
managerial competence, disposition to comply with regulations, and 
financial resources necessary to operate a new airline. FAA is 
responsible for certifying that the aircraft and operations conform to 
the safety standards prescribed by the Administrator--for instance, 
that the applicants' manuals, aircraft, facilities, and personnel meet 
federal safety standards. Also, if a merger or other corporate 
transaction involves the transfer of international route authority, 
DOT is responsible for assessing and approving all transfers to ensure 
that they are consistent with the public interest.[Footnote 21] 

In Creating the Largest U.S. Passenger Airline, a United-Continental 
Merger May Face Integration Challenges and Analysis of Some 
Overlapping Markets: 

If not challenged by DOJ, the merged United-Continental would surpass 
Delta as the largest U.S. passenger airline. As table 1 indicates, 
combining United and Continental Airlines would create the largest 
U.S. airline based on 2009 capacity as measured by available seat 
miles, and a close second based on total assets and operating revenue. 
The combined airline would also have the largest workforce among U.S. 
airlines based on March 2010 employment statistics, with a combined 
76,900 employees as measured by full-time-equivalent employees (table 
2). The airlines' workforces are represented by various unions, and in 
some cases the same union represents similar employee groups, such as 
the union for the pilots (table 3). Finally, the combined airline 
would need to integrate 692 aircraft (table 4). The two airlines share 
some of the same aircraft types, which could make integration easier. 

Table 1: Total Assets, Operating Revenue, and Capacity of Major U.S. 
Airlines (2009):

Capacity as measured by available seat miles (thousands): 217,166,074;

If not challenged by DOJ, the airlines would attempt to combine two 
distinct networks, United with major hubs, where the airline connects 
traffic feeding from smaller airports, in San Francisco (SFO), Los 
Angeles (LAX), Denver (DEN), Chicago O'Hare (ORD), and Washington DC 
Dulles (IAD) and Continental with hubs in Houston Intercontinental 
(IAH), Cleveland (CLE), Guam (GUM), and New York Newark (EWR), as 
shown in figure 2.

[End of figure] 

The amount of overlap in airport-pair combinations between the two 
airlines' networks is considerable if considering all connecting 
traffic; however, for most of the overlapping airport-pair markets 
there is at least one other competitor. Based on 2009 ticket sample 
data, for 13,515 airport pairs with at least 520 passengers per year, 
there would be a loss of one effective competitor in 1,135 airport-
pair markets[Footnote 22] affecting almost 35 million passengers by 
merging these airlines (see fig. 3).[Footnote 23] However, only 10 of 
these airport-pair markets would not have any other competitors in it 
after a merger. In addition, any effect on fares would be dampened by 
the presence of a low-cost airline in 431 of the 1,135 airport pairs 
losing a competitor.[Footnote 24] The combination of the two airlines 
would also create a new effective competitor in 173 airport-pair 
markets affecting almost 9.5 million passengers.

[End of figure] 

In examining nonstop overlapping airport pairs between United and 
Continental, the extent of overlap is less than for connecting 
traffic. However, the loss of a competitor in these nonstop markets is 
also more significant because nonstop service is typically preferred 
by some passengers. For example, based on January 2010 traffic data, 
the two airlines overlap on 12 nonstop airport-pair routes, which are 
listed in figure 4.[Footnote 25] For 7 of these 12 nonstop overlapping 
airport-pair routes (generally between a United hub and a Continental 
hub), there are currently no other competitors. However, of these 7 
airport-pair markets, all but the Cleveland-Denver market may have 
relevant competition between other airports in at least one of the 
endpoint cities. For example, passengers traveling from San Francisco 
(SFO) to Newark (EWR) could consider airlines serving other airports 
at both endpoints--Oakland or San Jose instead of SFO and John F. 
Kennedy (JFK) or LaGuardia instead of EWR.

If not challenged by DOJ, the combined airline could be expected to 
rationalize its network over time, including where it maintains hubs. 
Currently, the two airlines do not have much market share that 
overlaps at their respective hubs (see table 5). However, it is 
uncertain whether the combined airline would retain eight domestic 
hubs. There is considerable overlap between markets served by United 
out of Chicago (ORD) and Continental out of Cleveland (CLE). For 
example, 52 out of 62 domestic airports served by Continental from 
Cleveland are also served by United from Chicago (ORD).

Both United and Continental have extensive world wide networks and 
serve many international destinations. Between the two airlines, over 
100 international cities are served from the United States. The two 
airlines do not directly compete on a city-to-city route basis for any 
international destinations. Nevertheless, for international routes, 
airlines aggregate traffic from many domestic locations at a hub 
airport where passengers transfer onto international flights. In other 
words, at Newark, where Continental has a large hub, passengers 
traveling from many locations across the United States onto 
Continental's international flights. Likewise, United aggregates 
domestic traffic at its Washington Dulles hub for many of its 
international flights. Hence, a passenger traveling from, for example 
Nashville, may view these alternative routes to a location in Europe 
as substitutable. Continental and United serve many of the same 
international destinations in Europe and the Americas from their 
Newark and Dulles hubs, respectively. These destinations include 
Amsterdam, Brussels, Frankfort, London, Montreal, Paris, Rome, Sao 
Paulo, and Toronto. Similarly, both airlines also serve many 
international destinations from their Midwest hubs--most notably 
United's hub at Chicago and Continental's hub at Houston. Such 
destinations include Amsterdam, Cancun, Edmonton, London, Paris, San 
Jose Cabo, Tokyo, and Vancouver. In total, according to current 
schedules, they serve 30 common international destinations, 
representing 65 percent of their total international seat capacity. 
Whether service to international destinations from different domestic 
hubs will be viewed as a competitive concern will likely depend on a 
host of factors, such as the two airlines' market share of traffic to 
that destination and whether there are any barriers to new airlines 
entering or existing airlines expanding service at the international 
destination airports. 

To compete internationally, both Continental and United are part of 
the Star Alliance, one of the three major international airline 
alliances.[Footnote 26] In 2009, Continental left the SkyTeam Alliance 
and joined the Star Alliance. As part of joining this alliance, the 
Star Alliance members, including Continental, applied for antitrust 
immunity, which allows the member airlines to coordinate schedules, 
capacity, and pricing in selected markets. DOT has authority to 
approve these antitrust immunity applications,[Footnote 27] but DOJ 
may also comment if it has antitrust concerns. On June 26, DOJ filed 
comments that objected to immunity for the alliance in some markets 
and requested some conditions, called carve-outs, in which the 
immunity would not be granted. On July 10, 2009, DOT approved the Star 
Alliance application for antitrust immunity but with special 
conditions, including carve-outs.[Footnote 28] Among the markets not 
granted immunity were New York-Copenhagen, New York-Lisbon, New York-
Geneva, New York-Stockholm, Cleveland-Toronto, Houston-Calgary, 
Houston-Toronto, New York-Ottawa, and U.S.-Beijing.[Footnote 29]

[10] Collectively, U.S. airlines reduced domestic capacity, as 
measured by the number of seats flown, by about 12 percent from the 
fourth quarter of 2007 to the fourth quarter of 2009. As we reported 
in April 2009, to reduce capacity, airlines reduced the overall number 
of active aircraft in their fleets by eliminating mostly older, less 
fuel-efficient, and smaller (50 or fewer seats) aircraft. Airlines 
also collectively reduced their workforces by about 38,000 full-time- 
equivalent positions, or about 9 percent, from the first quarter of 
2008 to the first quarter of 2010. In addition to reducing capacity, 
most airlines instituted new fees, such as those for checked baggage, 
which resulted in $3.9 billion in added revenue during 2008 and 2009.

[15] Open Skies seeks to enable greater access of U.S. airlines to 
Europe, including expanded rights to pick up traffic in one country in 
Europe and carry it to another European or third country (referred to 
as fifth freedom rights). Additionally, the United States will expand 
EU airlines' rights to carry traffic from the United States to other 
countries. 

[16] Airlines also face potential challenges to mergers and 
acquisitions from DOJ's antitrust review, which is discussed in the 
next section. 

[17] The Guidelines were jointly developed by DOJ's Antitrust Division 
and the Federal Trade Commission and describe the inquiry process the 
two agencies follow in analyzing proposed mergers. The most current 
version of the Guidelines was issued in 1992; Section 4, relating to 
efficiencies, was revised in 1997. DOJ has proposed some changes in 
the Guidelines to better reflect its merger review process and the 
public comment period on these changes has been extended to June 4, 
2010. 

[18] See 15 U.S.C. § 18a(d)(1). Both DOJ and FTC have antitrust 
enforcement authority, including reviewing proposed mergers and 
acquisitions. DOJ is the antitrust enforcement authority charged with 
reviewing proposed mergers and acquisitions in the airline industry. 
Additionally, under the Hart-Scott-Rodino Act, DOJ has 30 days after 
the initial filing to notify companies that intend to merge whether 
DOJ requires additional information for its review. If DOJ does not 
request additional information, the firms can close their deal (15 
U.S.C. § 18a(b)). If more information is required, however, the 
initial 30-day waiting period is followed by a second 30-day period, 
which starts to run after both companies have provided the requested 
information. Companies often attempt to resolve DOJ competitive 
concerns, if possible, before the second waiting period expires. Any 
restructuring of a transaction--e.g., through a divestiture--is 
included in a consent decree entered by a court, unless the 
competitive problem is unilaterally fixed by the parties before the 
waiting period expires (called a "fix-it first"). 

[19] Market power is the ability to maintain prices profitably above 
competitive levels for a significant period of time. 

[20] United States Department of Justice and Federal Trade Commission, 
Horizontal Merger Guidelines (Washington, D.C., rev. Apr. 8, 1997). 

[21] 49 U.S.C. § 41105. DOT must specifically consider the transfer of 
certificate authority's impact on the financial viability of the 
parties to the transaction and on the trade position of the United 
States in the international air transportation market, as well as on 
competition in the domestic airline industry. 

[22] It is generally preferable, time permitting, to assess city-pair, 
rather than airport-pair, changes in competition. Some larger U.S. 
cities (New York, Chicago, Los Angeles, Washington D.C.) have more 
than one commercial airport that can compete for passenger traffic. 
DOJ generally considers the relevant market to be a city-pair 
combination. 

[23] For this airport-pair analysis, we considered any airport-pair 
market with less than 520 annual passengers to be too small to ensure 
accuracy. We defined an effective competitor as having at least 5 
percent of total airport-pair traffic. This is the same minimum market 
share that we have previously applied to assess whether an airline has 
sufficient presence in a market to affect competition. See GAO-08-845, 
p. 21 and 42. 

[24] We defined low-cost airlines as JetBlue, Frontier/Midwest, 
AirTran, Allegiant, Spirit, Sun Country, and Southwest. 

[25] In March 2010, Continental initiated nonstop service between Los
