Aer Lingus

Aer Lingus (ICAO: EIN) is the flag carrier airline of the Republic of Ireland, known for its distinctive shamrock logo.

Aer Lingus was founded by the Irish Government on April 15, 1936, and registered on May 22, 1936. Its inaugural flight took place on May 27, 1936, from Dublin to Bristol. The airline was privatized between 2006 and 2015 and is now a wholly-owned subsidiary of International Airlines Group (IAG).

The airline's primary operational base and main hub is Dublin Airport (DUB). It also maintains secondary bases at Cork Airport (ORK) and Shannon Airport (SNN). As of February 2025, Aer Lingus operates an all-Airbus fleet consisting of 76 aircraft, including the Airbus A320, A320neo, A321LR, A321XLR, A330-200, and A330-300. Aer Lingus Regional flights are operated by Emerald Airlines using ATR 72-600 aircraft. The airline's route network spans over 90 destinations across the UK and Europe, and 23 direct routes to North America, serving more than 11 million passengers annually. Aer Lingus employs a hybrid business model, offering mixed fare services on its European routes and full-service, two-class flights on transatlantic routes.

Aer Lingus is not a member of any major global airline alliance (e.g., Oneworld, Star Alliance, SkyTeam), having withdrawn from Oneworld in 2007. However, it has extensive codeshare and interline agreements with various carriers, including British Airways, American Airlines, JetBlue, United Airlines, KLM, Etihad Airways, and Alaska Airlines. The airline is also a part of the Atlantic Joint Business (AJB) with American Airlines, British Airways, Iberia, and Finnair. On its long-haul flights, Aer Lingus offers a Business Class with lie-flat seats, lounge access, priority services (dedicated check-in, priority boarding, fast-track security), and enhanced dining options. Economy class passengers on transatlantic flights can also enjoy individual touchscreen entertainment and personal charging points on most A330 aircraft.
