City of Derry Airport has said it is reviewing options to resume flights to London Stansted with a new airline as soon as possible - after the collapse of regional airline Flybmi.
The UK airline announced the move yesterday and cancelled all its flights with immediate effect.
The airline - which had 17 planes and employs 376 people - said Brexit and rising fuel costs are among the reasons for its demise.
Thousands of passengers who have had their travel plans disrupted are being advised to contact card companies and travel agents for refunds.

Yesterday evening, DUP MP Gregory Campbell said the new has been greeted with dismay in the northwest.
He said UK Transport Secretary Chris Grayling has told him he remains hopeful a new operator will agree to take on the route.
Unions in the UK have said news of the collapse is "devastating” for staff.
The British Airline Pilots' Association said it had no advanced warning of the decision to file for administration.
"Bolt out of the blue"
Meanwhile, passengers affected by the collapse have been voicing their frustration after having their travel plans thrown into chaos.
Civil engineer Danny McLaughlin had 14 flights booked with Flybmi between City of Derry Airport and London Stansted over the next seven weeks.

The father-of-two, who lives near Buncrana in County Donegal, said he was shocked when he received a text message telling him of the airline's demise.
"I know airlines and things have been saying this for quite a while but it just came as a bolt out of the blue," he said.
"I feel sorry for the staff. I haven't reached the angry stage yet, I probably will.
"I probably will get a bit annoyed as the weekend goes on. And on Monday morning when I can't get to work."
Meanwhile, Richard Edwards tweeted that he and his family had gone through security at Bristol Airport when he was told his Flybmi flight to Munich had been cancelled.
Great start to our holiday; en route with @Charlot53066691 and the family by taxi to Heathrow as our @flybmi from Bristol to Munich (which had previously been changed from Southampton) was cancelled with no explanation after we had gone through security! 😬😬😬
