AD PLACEMENT — CONTEXTUAL
Getting Between Concourses
Terminal 1 and Terminal 2 are linked by a covered landside walkway (roughly 8-10 minutes on foot) and a shuttle bus service for those who prefer not to walk, especially with heavy luggage. Because the terminals are landside-connected rather than airside-connected, transfer passengers must re-clear security when moving between terminals unless routed through a dedicated transfer path. Passengers connecting onto US-bound flights face an additional US Preclearance process (CBP screening plus a security recheck) inside Terminal 2, which functions like an extra immigration and security layer.
