Pro Tips
- The Dulles airport layout is confusing — the underground shuttles (mobile lounges + underground train) add 15 minutes to every connection.
- Budget 90 minutes minimum for any international connection at Dulles — customs, then re-security, then a tram ride is the standard routine.
- The new Metro Silver Line to Dulles is a game changer — the cheapest and most reliable way to downtown DC.
- IAD is often cheaper for transatlantic fares than DCA; check both airports when searching United's transatlantic routes.
- The historic main terminal (1962, Saarinen) is spectacular — arrive early just to appreciate the architecture.
- Dulles is large and spread out; gate assignments deep in Concourse C or D require significant walking.
- Long-term parking at the remote lots is affordable; shuttle buses run frequently to both terminals.
