Aer Lingus is the flag carrier of Ireland, operating a fleet of Airbus aircraft serving Europe and North America. It has a mixed business model, operating a low fare service on its European and North African routes and full service, two-class flights on transatlantic routes. In 2010 the airline flew 9.3 million passengers.
