The Washington to Chicago route at a glance
Washington Dulles is a United hub, and so is Chicago O'Hare, with the two about 590 miles apart and roughly two hours of flying time between them. Chicago is one hour behind Washington, and the capital region has three airports, Dulles, Reagan National and Baltimore-Washington, so it's worth comparing more than one if your final destination in the Washington area isn't right next to Dulles itself.
