Irish flag carrier Aer Lingus is a classic network airline. It offers free refreshments on long-haul flights to the United States, as well as guaranteed connections at Irish airports and beyond.

Aer Lingus has its main base at Dublin DUB Airport, but also offers frequent services from other Irish cities as well as Belfast BFS.

The planes are recognisable at a glance due to their traditional green livery with the St Patrick's shamrock - Ireland's national patron saint.
