✨ AI-Enhanced Insights
Shannon Airport (SNN/EINN) is a transatlantic gateway on Ireland's west coast in County Clare, about 25 km from Limerick and 90 km from Galway. It opened in 1939 and is famed as the site of the world's first duty-free shop, established in 1947. The airport also pioneered US preclearance in Europe, allowing passengers to clear US immigration and customs before departure.
💡 Local Tip
If you're flying to the US, Shannon's preclearance means you clear US immigration before boarding—so arrive at least 3 hours before departure and don't rely on last-minute shopping; once through preclearance, there are limited options and no turning back.
🚖 Getting There
Bus Éireann routes and Expressway services link the airport to Limerick, Ennis, and Galway; taxis rank outside arrivals, and major car rental desks are in the terminal. The M18 motorway is nearby, making driving to Limerick or Ennis straightforward, but there is no direct rail station at the airport—nearest train stations are in Limerick and Ennis. For early flights, pre-book a taxi or check the first bus times, as some services start later on Sundays and public holidays.
