Can I make a 55 minutes connection at IAD on an international flight?
55 minutes is below the 75-minute international MCT at Washington Dulles International. You may need to rush and could miss your connection. The AeroTrain is an airside underground train that connects the Main Terminal to Concourses A/B and C/D in about 5-8 minutes per leg, with no security re-screening required for onward transfers. Concourse Z, used for regional and some international flights, is only reachable by shuttle bus or mobile lounge from the Main Terminal, adding significant time; international arrivals must first clear immigration and customs at the Main Terminal before recheck, which is the single biggest time sink for connections.
What happens if I miss my connection at IAD?
United passengers who miss a connection should head to one of the Customer Service desks in Concourse B or C, or use the United app to self-rebook onto the next available flight, as IAD's hub status means frequent onward United departures.
