AD PLACEMENT — CONTEXTUAL
Getting Between Concourses
The Skytrain, an automated people mover, links T1, T2, and T3 airside in just 3-5 minutes per hop, with clear signage and frequent departures. Terminal 4 is not connected by Skytrain and instead uses a shuttle bus (about 10 minutes ride plus waiting) that requires passing through security and sometimes immigration again depending on flight status, making it the main variable in transfer timing.
