If you are flying soon, please be aware that it might be very busy at peak periods, so allow yourself plenty of time to check-in, go through Security screening and allow time to go through US Preclearance before your USA bound flight. USA flights depart from Terminal 2. At the moment, peak times at Security occur in Terminal 2 at 05.00 to 12.00 for morning and early afternoon flights. We normally advise passengers to allow 3 hours before a long haul flight departure, but it can take up to 3.5 hours at busy peak times.

Once you have cleared Dublin Airport security, the US Preclearance screens will direct you when to go to US Preclearance. Passengers should not  present to US Preclearance before their flight opens. Please see example below.
