AD PLACEMENT — CONTEXTUAL
Getting Between Concourses
All concourses are connected airside behind security via a continuous corridor with moving walkways, so no shuttle or train is needed. International arrivals (on Concourse E) go through Federal Inspection before re-entering the connected concourse system, meaning international-to-domestic connectors must clear immigration, customs, and a security recheck.
