The Best DC Airports

Before you call airlines looking for flights from Washington, DC, you should check with Orbitz.com.

The five parking lots at Ronald Reagan offer daily and hourly parking rates, and the airport charges $20 per day for parking in the long-term lots.

For $30, you can use valet parking.

Public Transportation Choices

The Metrorail and Metrobus make at least one stop at each airport every day. The stops are clearly marked around the city, and you can find maps that help you find the correct line.
