Offers to Orlando and New York are available for travel until 30 June 2022 with fares from Manchester to Barbados for travel until 30 April 2022.
Bill Byrne, Aer Lingus director of global sales, said: “There’s never been a better time to plan a springtime getaway to the Caribbean or US, especially since we continue to see consumer confidence grow in light of the recent removal of UK travel requirements.”
