What to expect
Aer Lingus is the flag carrier of Ireland, based at Dublin Airport, and it suits travellers flying between Ireland and Britain, continental Europe or North America. It was founded in 1936, and its first flight on 27 May that year took the de Havilland Dragon Iolar from Baldonnel to Bristol. The head office is in Cloghran, on the Dublin Airport grounds, and Lynne Embleton has been chief executive since April 2021. In 2025 it carried 11.34 million passengers.
International Airlines Group (IAG), which also owns British Airways and Iberia, took control on 2 September 2015. The airline describes its model as a hybrid: simpler fares on short European routes and a full two-class service across the Atlantic.
Dublin Airport is the main hub, with Cork as a base and flights also from Shannon and Belfast. The network of about 93 destinations covers the UK and continental Europe and transatlantic routes to cities in the United States and Canada. Since 17 March 2022 regional flights branded Aer Lingus Regional have been operated by Emerald Airlines under a franchise.
Key facts for travellers:
- Alliance: Aer Lingus is not in any alliance. It left oneworld on 31 March 2007 but has codeshare deals with airlines from oneworld, Star Alliance and SkyTeam.
- Fleet: about 63 aircraft: Airbus A320-family jets, including long-range A321LR and A321XLR models, and Airbus A330 wide-bodies.
- Cabins: Economy throughout, plus Business Class on long-haul flights.
- Loyalty programme: AerClub, which uses Avios points like other IAG airline programmes.
The shamrock on the tail has marked Aer Lingus aircraft since 1965, and the large white shamrock first appeared in the 1974 livery.
Travel tip: on European routes, Aer Lingus fares differ in what they include, such as checked bags and seat selection. Compare the fare options before you book. AerClub uses Avios, so points from other Avios programmes can be useful for Aer Lingus flights; check the current rules in your AerClub account.
