About flying from IAD

Washington Dulles International Airport is United Airlines' second largest hub and the Washington DC area's primary gateway for international travel. Dulles offers a significantly wider route network than Reagan National, particularly for transatlantic and international service.

United dominates Dulles with comprehensive domestic and international coverage. The airport also serves as a major entry point for international carriers from Europe, Asia, and the Middle East. For travelers heading abroad from the DC area, Dulles is almost always the most logical departure point.

The Silver Line Metro connection via shuttle and the Dulles Toll Road provide access from multiple points across Northern Virginia and DC.
