Washington Dulles International (IAD) – The main international hub, and where most Heathrow flights land. It’s about 45 minutes from downtown D.C., and offers the most international services and amenities.
Ronald Reagan Washington National (DCA) – Closer to the city centre (just 15 minutes by car or metro), but mainly serves domestic US flights. Great if you're connecting from another US city.
