Hundreds of travellers have been left stranded at Belfast, Cardiff and Glasgow airports, and at airports in Canada, after the collapse of the transatlantic budget airline Zoom.
The company said its problems were caused by what it called the horrendous price of fuel and the economic slowdown.
Passengers who booked with Zoom and who have not flown are advised to contact their credit card and debit card companies to try to claim a refund.
Zoom's cash crisis became apparent on Wednesday follow the grounding of a Zoom flight from Paris at Calgary airport in Canada. Glasgow airport was yesterday instructed by the UK's Civil Aviation Authority to detain a Halifax-bound flight over the non-payment of charges.
Zoom, founded by Scottish brothers John and Hugh Boyle, said it had attempted to secure a re-financing package that would have kept its aircraft flying. But the owners issued an apology to both travellers and its more than 600 staff after failing to strike a deal.
The airline is based at Gatwick in London and employs around 450 staff in Canada and 260 in the UK.
