Take the Metro. It is the most reasonably priced way to get into the city, costly just a couple of dollars per person. The Washington region's subway system is dependable, clean and modern. Blue and Yellow Line trains run from the airport at the concourse (Level 2) between terminals B and C. Hours are Monday to Thursday, 5 a.m. to 12:26 a.m.; Friday, 5 a.m. to 3:26 a.m.; Saturday, 7 a.m. to 3:26 a.m.; Sunday, 7 a.m. to 12:26 a.m. To get to the Metro entrance, follow the well-marked signs in the airport.
Take a taxi. Fares will run approximately $16 to $20 to downtown Washington. Taxi stands are immediately outside Terminal A and outside the arrivals level of terminals B and C. Follow the signs for ground transportation.
Take a shuttle service. SuperShuttle and other shuttle services can ferry you into the city for less than the cost of a taxi. Make a reservation in advance.
Hire a private car service. Arrangements should be made in advance. Confirm your reservation before boarding your flight to Washington.
Consult a volunteer at the airport's Travelers Aid stations. The desks are staffed for most of the day.
