Irish national carrier Aer Lingus has suspended services between Belfast City and Heathrow.
New legislation brought in post-Brexit has meant the airline’s operating licence, which ends at the end of October, will not be renewed.
Forsa, the Irish trade union which counts Aer Lingus staff amongst its members, has stated that staff on the thrice daily route, which has been in place since 2007, will be redeployed around the business.
British Airways will operate the route until a solution is found for the issue
In a statement, the CAA said: “After the UK left the European Union, all UK-based airlines have to operate under a UK operating licence which governs the traffic rights they may hold.
“Under current legislation and international agreement, EU carriers such as Aer Lingus, are not permitted to operate scheduled services on UK domestic routes.”
