Washington Dulles International is the costliest U.S. airport to fly out of domestically on average, per the latest Transportation Department data.
Why it matters: Add on a rideshare from D.C. and travel costs are about double what they are from Ft. Lauderdale (pro tip: take the Silver line).
By the numbers: Average domestic airfare out of Dulles ran $473 in the third quarter of 2024.
- That's more than $100 over the average for all U.S. airports, $366.
Meanwhile, domestic airfare out of Reagan National Airport flies just below the national average at $359.
