Finding a really good deal on a flight is always exciting. But despite whatever budget travel hacks you might use, one thing that can make it all more challenging is which airport you fly out of.

CivMetrics, a nonprofit journalism organization, collected the average cost of flights in and out of the 100 busiest U.S. airports based on 2022 Q3 data from the Bureau of Transportation Services.

Among the busiest airports, Ted Stevens Anchorage International in Alaska was the most expensive, with an average flight price of $540. On the other end, St. Pete Clearwater International in Florida, where flight costs average around $147, ranked as the cheapest airport.
