The Irish flag carrier will up its three-times-weekly Manchester-Orlando service to four-times-weekly from 18 December 2024 to 8 January 2025, including a Christmas Day flight.
Chief customer officer Susanne Carberry said the extra flights to Orlando would complement its existing transatlantic service, which she said was "continuing to prove popular with customers in the north of England".
Aer Lingus will also service Barbados and New York from Manchester this winter, as well as Belfast and Dublin.
