This Mid-Atlantic Airport Is Quietly One of the Cheapest in the Region

Maryland's primary commercial airport is one of the more competitive departure points in the mid-Atlantic region—and a meaningful value compared to the other airports serving the greater Washington, D.C. area.

Only In Your State analyzed recently released Bureau of Transportation Statistics data, and Baltimore/Washington International Thurgood Marshall Airport (BWI) averaged $366.07 per domestic ticket in 2025—ranking 32nd most affordable nationally out of 100 airports. That's $20.93 below the national average of $387.

BWI vs. the Other DC-Area Airports

The greater Washington, D.C. metro area is served by three major airports, and BWI is the clear winner on price. Ronald Reagan Washington National Airport (DCA) averaged $375.92, ranking 38th—$9.85 more per ticket than BWI. Washington Dulles International Airport (IAD) averaged $468.84, ranking 97th nationally—$102.77 more per ticket than BWI.

The gap between BWI and Dulles is particularly striking. At $102.77 per ticket, a family of four traveling from BWI instead of Dulles would save over $411 on airfare alone—enough to cover a night or two at the destination.

Beyond the base fare savings, BWI’s layout and accessibility offer practical advantages for budget-conscious commuters. Convenient transit links like the MARC Train and Amtrak directly connect the terminal to Washington, D.C., and Baltimore, making ground transportation seamless. When combined with cheaper long-term parking options than at DCA and IAD, choosing BWI often yields even greater overall savings for Mid-Atlantic families and frequent flyers alike.

BWI ranked 23rd nationally by passenger volume, which helps explain its competitive pricing. It's a high-traffic airport with a strong Southwest Airlines presence and the resulting fare competition that keeps prices below what you'd pay at Reagan National or Dulles.

What Maryland Travelers Should Know

For Maryland residents, BWI is already a good default choice. It outperforms two of its closest competitors on price while serving a wide range of domestic destinations with strong frequency.

The 32nd ranking means Maryland has one of the better airport-cost situations of any state in the Northeast or Mid-Atlantic. Paired with smart booking habits and an early start on your trip planning, BWI gives Maryland travelers a genuine cost advantage over much of the region.

Expanding options across alternative regional hubs can yield additional savings depending on your final destination, but for local travelers, BWI remains hard to beat. Taking advantage of flexible travel dates, monitoring mid-week fare drops, and booking directly through carrier promotions can stretch your budget further once you've already secured BWI’s baseline cost advantage.

This data reflects 2025 averages from the Department of Transportation, released in May 2026. Current fares may be higher due to rising jet fuel costs. Knowing how to find the best available fares can stretch that advantage even further.
