Aer Lingus has pushed back the planned launch date for its Manchester-US routes for two months.
The carrier had planned to operate services to New York JFK and Orlando on 29 July but has now set a new start date of 30 September.
Its Manchester-Barbados service is still scheduled to start as planned 20 October.
Aer Lingus apologised and said its team is contacting customers directly to offer a full refund, rebooking for an alternative service or the option of a voucher with an additional 10%, for use across the Aer Lingus network over the next five years.
