๐ข Terminal Information
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.

๐ข Terminal Information
Dublin Airport (DUB) is the premier international gateway to Ireland and serves as a major European aviation hub, facilitating millions of passengers annually. Located just north of Dublin city center, the airport is the primary base for the national carrier Aer Lingus and the leading low-cost airline Ryanair. Its strategic position on the edge of Europe makes it a critical node for transatlantic travel, offering extensive connections between North America, the UK, and continental Europe.
The airport infrastructure is organized into two primary passenger terminals, T1 and T2, which are conveniently connected both landside and airside. Terminal 1 is the older of the two and primarily handles short-haul flights and low-cost carriers, featuring a high-volume departures area and a diverse range of retail and dining options. Terminal 2, which opened in 2010, is a state-of-the-art facility that serves as the main hub for Aer Lingus and handles the majority of long-haul and international traffic. The transition between terminals is well-signposted and manageable by foot, ensuring a streamlined experience for connecting passengers.
A standout feature of Dublin Airport is its world-class U.S. Preclearance facility located in Terminal 2. This allows passengers bound for the United States to complete all U.S. immigration, customs, and agriculture inspections before departure, enabling them to arrive in the U.S. as domestic passengers and avoid long queues upon arrival. The airport also offers a high-end passenger experience through "The Loop" retail zone and several premium lounges, including the unique 51st&Green lounge specifically for U.S.-bound travelers. With frequent bus and coach links to the city center and other major Irish cities, DUB remains an exceptionally accessible and efficient entry point to the Emerald Isle.
