US Preclearance

Shannon is the first airport in the world, outside of the Americas, to offer Full US Preclearance facilities to passengers travelling to the USA.

This new upgraded service allows US bound passengers to undertake all immigration, customs and agriculture inspections at Shannon prior to departure, making your arrival in the US easier and faster.

  • Your baggage is checked through to your final destination, without the need for pick up/drop off.
  • Arriving as a domestic passenger allows for a faster process though the airport.
  • Shorter connecting times mean you can reach your final destination earlier.

Reporting Times to US Preclearance

Passengers must clear all formalities a minimum of 60 minutes before the scheduled departure time of your flight. Please allow adequate time for this process as failure to report on time may affect your ability to travel.

Permitted Food Items
