WASHINGTON (AP) — A government watchdog confirmed Wednesday what airline passengers are finding when they try to book a flight: Service to communities of all sizes is declining, but especially to small and medium-size airports.

There are fewer flights and fewer airplane seats available than there were seven years ago, the Government Accountability Office said. Smaller destinations were particularly affected, with flights down as much as 24 percent and seats down as much as 18 percent since 2007. Flights have also declined 9 percent and seats 7 percent at large airports.
