AD PLACEMENT — CONTEXTUAL
Check your concourse letter as soon as you land — A, B, and C all require a train ride from the main terminal.
If arriving internationally, budget extra time since you must clear Customs and Border Protection at Concourse A and then re-clear security to reach your next flight.
Use the pedestrian bridge to Concourse A only as a backup; the train is faster unless there's a service delay.
Southwest, United, and Frontier gates cluster on different concourses, so confirm your airline's home concourse before you deplane.
Download the United or Denver airport app for real-time gate and train updates, since gate changes are common during peak banks.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
The Automated Guideway Transit (AGT) train links the main Jeppesen Terminal to Concourses A, B, and C, with each leg taking roughly 2-4 minutes plus wait time. Concourse A can also be reached via an above-ground pedestrian bridge (about a 10-minute walk) if the train is delayed. All connections stay within one sterile zone, so passengers arriving on a domestic or international flight who cleared security once do not need to re-screen unless they exit through customs first.
