Aer Lingus carried a record 2.5 million passengers on its transatlantic routes in 2019.
The airline serves a total of 14 North American destinations from its two airports in Ireland, Shannon and Dublin, which both offer preclearance facilities to the US.
The five most popular airports in the US for Aer Lingus passengers were JFK, New York; Logan Airport, Boston; O’Hare International, Chicago; San Francisco, California and Orlando, Florida.
The five most popular UK departure airports via feeder flights were Manchester, Birmingham, Heathrow, Edinburgh and Glasgow.
Aer Lingus Chief Commercial Officer Dave Shepherd said: “We are delighted to mark 2.5 million North Atlantic guests so far in 2019.
“The achievement of this record number of North Atlantic guests sees us building towards our ambition to be the leading value carrier across the North Atlantic.
“Achieving this goal involves the introduction of new aircraft, new routes, increasing our capacity, as well as maintaining our commitment to delivering our four-star service for guests.
“This summer, for example, we welcomed two new Airbus A321neo LRs to our fleet.
“We are due to take delivery of more of these next generation aircraft in 2020, which we believe will transform our long haul offering with the ability to serve long haul destinations with narrow body aircraft.
“This not only opens up new North American route possibilities for Aer Lingus in the future, but also offers seamless connection onwards to Europe for guests travelling to Ireland from North America.”
