Tips for 1½ hr Connections
If your connection involves a US-bound flight, budget significant extra time for US Preclearance, which includes full CBP interviews and a separate security screening.
Check whether your onward flight departs from the same terminal, since T1-T2 transfers require exiting and re-entering security.
Security queues can back up badly at peak morning and early evening banks, so use Fast Track if your ticket qualifies.
Signage for 'Flight Connections' is present but the walk between terminals is longer than it looks on the map, so don't cut it close.
Aer Lingus flights are concentrated in Terminal 2, so same-airline connections are usually simpler than cross-terminal itineraries.

Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
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.
