The British CAA has advised that Flybe, the British regional airline, has entered administration.
All its flights are canceled and it urged passengers not to go to airports.
For flights operated by franchise partners, passengers should make contact with their airline, it said.
Commenting, Richard Moriarty Chief Executive at the UK Civil Aviation Authority, said: “This is a sad day for UK aviation and we know that Flybe’s decision to stop trading will be very distressing for all of its employees and customers.
“We urge passengers planning to fly with this airline not to go to the airport as all Flybe flights are canceled. For the latest advice, Flybe customers should visit the CAA website or the CAA’s Twitter feed for more information.
“Flybe also operated a number of codeshare partnerships with international airlines. If you have an international ticket you should make contact with that airline to confirm your travel arrangements.”
