One of Europe’s largest regional airlines has stopped ticket sales and cancelled all flights.

The move by Flybe airlines could signal a potential bankruptcy. According to a notice on its website, the company has entered administration, a form of protection from creditors when a company becomes insolvent. No flights are being rescheduled and Flybe is not able to help passengers book on another airline. Anyone who scheduled a Flybe flight is encouraged to not go to the airport unless they have arranged an alternative flight.

About 75 thousand Flybe customers who had future bookings are affected by flight cancellations. The UK’s civil aviation authority announced that Flybe passengers who could no longer use their tickets would be offered discounts on flights with other airlines. Flybe had been Europe’s largest regional airline prior to COVID, carrying about 8 million passengers a year via 81 airports throughout the up and Europe.

The company failed to build back its business amid lingering effects the lockdowns had on the airline industry and competition from more established low-cost operators.
