Passengers from Northern Ireland are amongst those affected by the collapse of British travel company, Goldtrail.
A flight from Belfast International to Turkey was cancelled today leaving passengers stranded.
The Consumers Association in Ireland says passengers affected should contact the Civil Aviation Authority (CAA) in Britain to seek a refund.
Around 16,000 tourists were abroad when Greece and Turkey specialist Goldtrail went into administration yesterday, the CAA confirmed.
The CAA said it was making arrangements to fly customers home at the end of their holiday under its ATOL (Air Travel Organiser's Licensing) scheme.
In a statement issued on its website last night, the aviation regulator said: ‘The CAA has taken steps to protect customers booked with Goldtrail Travel Limited after the company ceased trading this evening.
‘Goldtrail Travel Ltd, trading as Goldtrail Holidays, Goldtrail Travel and Sunmar, held ATOL licence 4684 and was based in New Malden, Surrey. It operated flights and holiday packages from many UK airports to Turkey and Greece. It sold mainly through travel agents.
‘The CAA, under its ATOL scheme, is making arrangements for customers abroad to travel home at the end of their holidays.’
The majority of flights home from Turkey will operate as normal, the CAA said, but outbound flights from UK and Northern Irish airports were cancelled.
