Given Shannon Airport’s unique status with the US and ability to offer pre-clearance to those travelling across the Atlantic, many of the airlines operating here focus on transatlantic service. However, the network of flights offered extends to include several destinations in Europe and the surrounding area.


Shannon Airport is served by Aer Lingus and Ryanair, along with US-based airlines including Continental and Delta. Many of the transatlantic routes are only available on a seasonal basis.


These are some of the most prominent airlines offering regular or seasonal service out of Shannon Airport:


Aer Lingus

Ireland’s national carrier operates service to London-Heathrow throughout the year, along with seasonal connections across the Atlantic to New York and Boston. Aer Lingus Regional operates routes to cities in the UK, but in Aer Arann planes.


Air Transat

This transatlantic service provider operates a single route to Toronto’s Pearson Airport on a seasonal basis.


Continental Airlines

Continental is another of the main transatlantic airlines operating through Shannon Airport, with flights connecting to Newark New Jersey. Continental passengers were the first to use the US pre-clearance facilities at Shannon Airport.


Delta Airlines

This US airline runs a seasonal route to and from New York’s JFK Airport.



Europe’s leading discount flier operates a network of routes from Shannon Airport to cities in the UK as well as destinations in Eastern Europe, the Canaries and the Balearics.
