About Aer Lingus
Aer Lingus (IATA code: EI) is the flag carrier of Ireland, founded in 1936 and part of International Airlines Group since 2015 alongside British Airways and Iberia. Its hub is Dublin, with a secondary base at Shannon.
Its defining advantage for American travelers is US preclearance. Dublin and Shannon both host US Customs and Border Protection facilities, so you complete US immigration before boarding and arrive back in the United States as a domestic passenger — a significant time saving, especially with an onward connection.
Aer Lingus serves North America from New York JFK, Newark, Boston, Chicago, Hartford, Los Angeles, Orlando, San Francisco, Seattle and Washington. It is not a member of a global alliance, but it interlines widely and its fares to Europe via Dublin frequently undercut the legacy carriers. Our agents check that routing whenever a client is heading to the UK or continental Europe.
