AD PLACEMENT — CONTEXTUAL
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.
