We're delighted to be able to offer you the ultimate time-saving service – U.S. pre-clearance facilities at Dublin airport from Terminal 2. This means that if you're flying to the U.S., you can clear not only U.S. immigration, but also full U.S. customs and agriculture controls.

Yes, Aer Lingus passengers departing from Dublin (DUB) or Shannon (SNN) airports benefit from U.S. Preclearance, which is one of the biggest advantages of flying the Irish flag carrier. This means that you undergo U.S. Immigration, Customs, and Agriculture inspections before you even board the plane in Ireland. When you arrive in the United States (at airports like JFK, Boston, or Chicago), you land as a "domestic" passenger. You simply walk off the plane, pick up your bags from the standard domestic carousel, and walk straight out of the airport without waiting in any customs lines. In 2026, the Dublin Preclearance facility has been upgraded with biometric "facial recognition" gates, making the process faster than ever. It is important to note that you should arrive at Dublin Airport at least 3 hours before your flight to allow enough time for both standard security and the U.S. Preclearance process, as the Preclearance wing has its own dedicated security screening. This service is a "game-changer" for those with tight domestic connections in the U.S., as it eliminates the risk of missing a flight while stuck in a 2-hour customs queue at a busy American hub.
