About Aer Lingus
Aer Lingus (IATA: EI) is Ireland's flag carrier, founded in 1936 and headquartered at its primary hub, Dublin Airport (DUB). Now part of International Airlines Group (IAG) — the parent company of British Airways, Iberia, and Vueling — Aer Lingus operates a mixed fleet of Airbus A320-family aircraft on short-haul European routes and A321LR/A330 widebodies on transatlantic services to North America.
Aer Lingus is not a member of any global airline alliance, but maintains codeshare and interline agreements with oneworld carriers such as British Airways and American Airlines. The airline is best known as a major transatlantic gateway between Ireland and North America, helped by US Customs and Border Protection preclearance facilities at Dublin and Shannon airports — allowing passengers to clear US immigration before departure. FareOptic compares Aer Lingus fares across Europe and North America so you always find the lowest EI ticket price for your journey.

Tips to Book Cheap Aer Lingus Flights
- 1.Aer Lingus DUB–JFK and DUB–BOS fares are often the cheapest way across the Atlantic — book 8–12 weeks ahead for the best Economy pricing.
- 2.Use Dublin or Shannon's US preclearance to skip immigration lines on arrival in the US — a major time-saving advantage of flying Aer Lingus.
- 3.Aer Lingus Business Class on the A321LR and A330 offers lie-flat seats at fares often lower than competing transatlantic carriers.
- 4.Connect through Dublin (DUB) for onward European travel — Aer Lingus' short-haul network covers major UK and mainland Europe cities.
- 5.AerClub members can earn and redeem Avios across British Airways and Iberia as well as Aer Lingus, thanks to shared IAG membership.
- 6.Aer Lingus is not part of a global alliance, so compare its fares independently — don't assume oneworld award availability applies directly.
- 7.Book early for peak transatlantic summer travel (June–August) as Aer Lingus capacity from Dublin fills quickly on North American routes.
- 8.Use FareOptic to compare Aer Lingus against British Airways and Delta for Ireland–US routes, and against Ryanair for short-haul European connections.
