Getting between terminals
T2 · T3connected airsideT4T5 · T5A · T5B · T5Cconnected airside
T2 and T3 share the Central Terminal Area and are joined by an underground walkway, roughly 10 minutes on foot. T4 and T5 have no walkway to anything and are reached by flight-connection bus. A temporary exemption from re-screening on airside transfers has applied since January 2025 — treat inter-terminal transfers as possible but not routine, and do not promise them.
