Shannon Airport (SNN)

Shannon Airport operates from a single terminal building serving approximately 2 million passengers annually with the unique distinction of offering full US preclearance facilities - the only European airport outside Dublin to provide this service. The terminal features modern facilities across two levels with clear separation between EU/EEA and non-EU areas. Shannon's historic significance as a transatlantic refueling stop has evolved into a strategic hub for US-Ireland connections. Walking distances are compact: check-in to gates typically 5-10 minutes, maximum gate-to-gate connections 12-15 minutes. Security processing is generally efficient taking 10-20 minutes with minimal queues outside peak travel periods. US preclearance adds 30-60 minutes but allows passengers to arrive in the US as domestic passengers. Immigration for non-EU passengers typically takes 10-25 minutes. The terminal offers Irish specialty shops, duty-free, restaurants featuring local cuisine, and comfortable seating areas. The airport's location on Ireland's west coast provides excellent access to the Wild Atlantic Way, Cliffs of Moher, and western Ireland attractions. Ground transportation includes buses to Limerick, Galway, and other western Ireland destinations.
