Dublin Airport Guide

Arrive at least 120 minutes before a domestic flight from DUB, and 180 minutes before an international flight. Peak-time TSA waits at DUB can hit 30+ minutes, so add buffer.

DUB requires at least 45 minutes for domestic-to-domestic connections and 45 minutes for international-to-domestic connections. All terminals are airside-connected, so you do not need to re-clear security when changing terminals.

Budget 45 min for same-terminal transfers and 1 hr for different-terminal transfers at DUB via Single connections area under one roof; Terminal 1 and Terminal 2 are a 5-minute walk apart, linked airside and landside. OAG airport standard is a flat 45 minutes for every sector. Aer Lingus files (and publishes) higher route-specific minimums at Terminal 2 that the OAG data confirms to the minute. At Dublin 'domestic' means within Ireland, so Europe-to-US and Europe-to-Europe connections are both international-to-international. The Terminal 2 Flight Connections route has no second security screen; US Preclearance lets passengers arrive in the US as domestic passengers.

With 3 hours you should stay inside DUB. A 6-hour layover is enough to leave the airport briefly. Round-trip to the city center is about 50 minutes plus re-screening. Dublin city centre is about 14-30 min by coach (Dublin Express or Aircoach; no rail link). A 6+ hour layover is comfortable for a quick visit. US-bound passengers should not leave, as preclearance needs the full 3 hours.
