Holiday firm Thomas Cook has gone out of business, leaving more than 150,000 holidaymakers stranded abroad and millions more with their holidays cancelled.

If you are on holiday with Thomas Cook, or have one booked, here's what you need to do.

I am abroad with Thomas Cook right now. How do I get home?

The UK Civil Aviation Authority has launched the UK's largest peacetime repatriation operation, chartering a fleet of aircraft from around the world to bring passengers back to the UK.

A spokesman said: "Due to the significant scale of the situation some disruption is inevitable, but the Civil Aviation Authority will endeavour to get people home as close as possible to their planned dates. This will apply to both ATOL protected passengers and those who are not affected." 

It has launched a dedicated website,, where passengers stranded abroad can find details about their own flights home.

If you're abroad with Thomas Cook now, you shouldn't travel to the airport until your flight home has been confirmed on this website.

If you're ATOL protected, you will be able to make claims for the cost of replacing ATOL protected parts of their trip, or for out of pocket expenses as a result of delayed flights home. The Civil Aviation Authority will be launching a service to manage all refunds by the end of the month.

My hotel is worried they won't be paid and are demanding money. What should I tell them?

The UK CAA is also contacting hotels accommodating Thomas Cook customers, who have booked as part of a package, to tell them that the cost of their accommodation will also be covered by the Government, through the Air Travel Trust Fund/ATOL cover. If your hotel is asking you for money you are advised NOT to pay them but instead to contact the CAA's helpline on +44 1753 330 330 so that they can make the arrangements.

I'm due to fly out with Thomas Cook today. Can I still go on holiday?

No, unfortunately all flights with Thomas Cook have been cancelled. Customers are advised not to go to the airport. If you choose to book an alternative outbound flight, you won't be compensated for it and you won't be eligible for a repatriation flight back.

I have a holiday booked with Thomas Cook that I've already paid for. How do I get my money back?

If you're ATOL protected, you will be entitled to a full refund on your cancelled holiday - the Civil Aviation Authority will be launching a service to manage all refunds by the end of the month.
