  • Reagan Airport is the closest airport to downtown Washington DC at just a 13-minute drive across the Potomac River. This airport is well connected to the public transport system on the Blue Line and Yellow Line of the Metrorail, which will take you into the city centre. You can find the station between Terminals B and C.

To help connect travellers to the city, you can catch the Silver Line Express bus to the Wiehle-Reston East station on the Silver Line. This service costs approximately $5 a ticket (£3.70), plus the metro ticket.
  • If you’re travelling with kids, Dulles Airport has partnered with NASA to provide an interactive gaming area on Concourse B near Gate B70. Here your children, or children at heart, can play games and learn while waiting to fly. The airport website also has activity sheets free to print off.
  • For those who need a phone charger after their flight to Washington DC, Reagan Airport has charging stations near the gates, in the restaurant area and at the baggage claim level. You will find these by looking for the "Power Up" sign.

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller
At KAYAK we don’t set prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find on occasion that certain prices are no longer available.

More questions or if you have a bad price to report to us
Please send us an and someone from our team will get back to you promptly.
