Highlights

The U.S. passenger airline industry is vital to the U.S. economy. Airlines directly generate billions of dollars in revenues each year and catalyze economic growth. Interest in the airlines' ability to weather volatile fuel prices and the economic recession led to congressional requests for a GAO review. GAO examined how (1) the financial condition of the U.S. passenger airline industry has changed, the principal factors affecting its condition, and its prospects for 2009; (2) airlines have responded to the factors affecting their financial condition; and (3) changes in the industry have affected airports, passengers, and the Airport and Airway Trust Fund (Trust Fund), which funds the Federal Aviation Administration's (FAA) capital programs and most of its operations. To do this, GAO analyzed financial and operating data, reviewed studies, and interviewed airline, airport, and FAA officials and other experts. The Department of Transportation (DOT) provided technical comments, which were incorporated as appropriate.

Matter for Congressional Consideration

Matter Status Comments
Given the inherent uncertainty of forecasting revenues and the deteriorating uncommitted balance of the Trust Fund, Congress may wish to consider working with FAA to develop alternative ways to reduce the risk of overcommitting budgetary resources from the Trust Fund. Better matching of actual revenues to the appropriation from the Trust Fund would help to ensure sufficient Trust Fund revenues are available to cover all the obligations that FAA has the authority to incur, thus reducing the risk of disruptions in funding for aviation projects and programs. One approach would be to appropriate less than 100 percent of the forecasted revenues, especially until a sufficient surplus is established to protect against potential disruptions in revenue collection. This change would reduce the likelihood that FAA would incur obligations in excess of the cash needed to liquidate these obligations and thus reduce the risk of delaying or terminating projects. Another approach would be to target a minimum level for the Trust Fund's uncommitted balance and base appropriations on the goal of maintaining that target level. This change would make it more likely that uncommitted resources would be available to FAA in the event that actual revenues fell short of forecasted revenues in a future year. Either approach would result in fewer available resources for some period of time, unless a General Fund contribution made up the difference.
Closed - Implemented
In 2009, GAO reported that the passenger airline industry's contraction reduced revenues for the Airport and Airway Trust Fund (Trust Fund) and contributed to a decline in the fund's uncommitted balance. Appropriations from the Trust Fund are based on FAA's projected revenues, and actual revenues have been less than FAA's forecast, resulting in the uncommitted balance falling from about $7.3 billion at the end of fiscal year 2001 to about $1.4 billion at the end of fiscal year 2008, and may fall further. If the uncommitted balance declines close to zero, FAA might have to delay capital programs unless additional funding is made available. Given the inherent uncertainty of forecasting revenues and the deteriorating uncommitted balance of the Trust Fund, GAO suggested that Congress consider not making the full amount of forecasted receipts available from the Trust Fund. The FAA Modernization and Reform Act of 2012 (Pub. L. 112-95) enacted on February 14, 2012, included a provision that GAO recommended to Congress for consideration. Section 104 (a) of the Act, limits the budget resources made available from the Trust Fund to 90 percent of the receipts, as suggested as one option in GAO's report, as well as any prior year differences between actual Trust Fund receipts and appropriations from the Trust Fund. This provision could provide greater protection against overcommitting Trust Fund resources, that is, to help ensure that Trust Fund revenues would be sufficient to cover FAA's expenditures.
