Tips for 50 min Connections
If arriving internationally, budget extra time for the Customs and Border Protection line at the D/E Federal Inspection Station before you can even head to your next gate.
Terminals A, B, and C are all linked by the free Terminal Link train, so domestic-to-domestic connections are usually straightforward if you allow for train transit and walking.
United's hub operations mean gate changes are common at peak hours, so check the app frequently rather than relying on your original gate assignment.
Terminal E can feel like a long walk from the train station to the gates, so add a buffer if your connection lands there.
TSA PreCheck lines are typically much shorter and can save 15-20 minutes versus standard security during peak banks.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
The Terminal Link automated train connects Terminals A, B, C and the D/E international complex airside, with rides typically taking 5-10 minutes between stops plus walking and waiting time. International arrivals must first pass through Customs and Border Protection in the D/E Federal Inspection Station before any connecting travel, and there is no sterile international-to-international transit corridor, so U.S.-bound international connections always require a full recheck.
