You might be adding hundreds of dollars to the cost of your flight depending on the airport you choose for your travels.
A recent ranking analyzed U.S. airports based on average domestic airfare - and it revealed major price differences, depending on where travelers begin their journey.
The analysis took airfare data for the 200 busiest airports in the United States and compared average ticket prices across regions and carriers during the first half of 2025. It used data from the Bureau of Transportation Statistics (BTS) and interpreted it to produce an airport ranking.

Travelers who are flexible with departing locations may find cheaper fares by departing from smaller, secondary airports instead of major hubs, the data indicates.
Among the nation's most affordable departure points overall, St. Petersburg-Clearwater (PIE), Orlando Sanford (SFB) and Punta Gorda (PGD) topped the list - each posting average fares well below $150.
MidAmerica St. Louis Airport (BLV) and Rickenbacker International Airport (LCK) rounded out the top five, with all five airports served primarily by ultra-low-cost carriers such as Allegiant and Sun Country.
The report noted that "not every traveler is so lucky to live near one of the most affordable airports."

It added that "some smaller markets - particularly resort destinations and mountain towns - command some of the nation's highest fares, thanks to limited airline competition and seasonal demand."
The report also shared a key caveat.
"Even within the same metro area, airfare costs can vary dramatically depending on which airport you choose. For travelers in multi-airport regions, those differences can translate into serious savings. Of course, not all airports serve the same destinations, and differences in travel time and parking fees should be considered when deciding which airport to depart from."
Using fare alerts, booking several weeks in advance and paying close attention to baggage fees on budget airlines can help maximize savings, the analysis found.
