When considering where to fly from, the choice of airport can significantly impact your ticket price—sometimes adding hundreds of dollars to your fare.
A recent analysis of U.S. airports evaluated average domestic airfares, revealing notable disparities based on the departure airport. This examination looked at data from the Bureau of Transportation Statistics (BTS) for the two hundred busiest airports in the U.S., comparing ticket prices for various airlines and regions during the first half of 2025.
According to the findings, the average domestic airfare across the country is about $391, which represents a slight decrease of 1.3% from the previous year. Intriguingly, when adjusting for inflation, air travel is actually about 36% less expensive compared to 1995.
The report identified the major U.S. airports with the highest and lowest average domestic airfares.
Most Expensive Major Airport
Washington Dulles International Airport (IAD) takes the top spot as the priciest major airport in the United States, where the average domestic airfare hovers around $475.
Following closely is Salt Lake City International Airport (SLC) with average fares near $461, and Charlotte Douglas International Airport (CLT) showing average prices around $445.
Most Affordable Major Airports
On the flip side, Fort Lauderdale-Hollywood International Airport (FLL) stands out as the most affordable major U.S. airport, with an average fare of about $281 as of early 2025.
Orlando International Airport (MCO) ranks right behind it, with average airfares of about $289. Meanwhile, Harry Reid International Airport (LAS) also offers lower fares, averaging around $291.
Interestingly, travelers with flexible departure options might want to consider secondary airports, which often have cheaper flights. Airports like St. Petersburg-Clearwater (PIE), Orlando Sanford (SFB), and Punta Gorda (PGD) offer average fares well below $150.
Other airports like St. Louis (BLV) and Rickenbacker International (LCK) also rank as cost-effective options for travelers, primarily serviced by low-cost carriers.
There are, however, limitations to this accessibility. The report highlights that not all travelers are conveniently located near an affordable airport.
It’s also worth noting that smaller markets, particularly in resort areas, can sometimes have high fares due to limited competition and seasonal demand.
A significant takeaway from the report is that airfare can vary considerably even among airports within the same metropolitan area. This variability could lead to substantial savings for travelers—though other factors like destination, parking, and travel time should also be considered.
To maximize potential fare savings, the analysis suggests utilizing fare alerts, booking tickets well in advance, and being mindful of baggage fees, particularly with low-cost airlines.
Meanwhile, the federal government has entered a partial shutdown, which could disrupt air travel as the TSA, responsible for security checks at approximately 440 airports, faces operational challenges.
