Airline Competition: Fares and Concentration at Small-City Airports

Pursuant to a congressional request, GAO examined fares and competition at 39 airports serving small cities to determine whether: (1) fares from small-city airports were higher than fares from major airports; (2) market concentration at small-city airports was associated with higher fares; and (3) market concentration at major destination airports affected fares on routes from small-city airports.
