Plans to develop a Derry to Dublin flight route have been scrapped.
Isle of Man airline, Citiwings, had been scheduled to launch the long-awaited service in April this year.
However, a spokesperson for City of Derry Airport said the EU referendum result had led to a significant devaluation in the pound, making the operation of the route "commercially difficult".
A spokesperson for City of Derry Airport said:
"The proposed new route was due to be part funded by the Governments Regional Air Connectivity Fund, but also required additional funding.
"The impact of the referendum vote in favour of BREXIT has led to significant devaluation in the pound sterling, given that the airline industry operates in Euro and Dollars, the economics of the route deteriorated to a position which has made the operation of this route commercially difficult.
"While this is clearly disappointing news for the Airport and for the passengers that have expressed an interest in this service, the Airport acknowledges the strong demand for a Dublin service and remains committed to continue discussions with a number of other carriers in an effort to secure this routes."
