Aer Lingus flyers with cancelled Stobart Air flights can get refunds, rebook or make insurance claims to get their money back and try to save their holidays.
Stobart Air was a franchise of Irish airline Aer Lingus, and ran flights on 12 of its routes. But the company stopped trading on Friday, June 11, cancelling all flights.
These flew from Dublin and Belfast City airports to terminals including East Midlands, Edinburgh, Exeter, Donegal, Glasgow, Leeds Bradford, Newquay and Manchester.
Customers with cancelled flights can get a full refund directly from Aer Lingus.
The airline has asked customers booked on Stobart flights not to come to the airport, but to check the Aer Lingus website for refund information at www.aerlingus.com.

Stobart customers can also swap to an alternative flight, depending on the route.
Aer Lingus has picked up flights to five of Stobart's destinations, and BA City Flyer will run two for at least a week, with the other routes still being worked on.
Customers can check possible alternative flights on the Aer Lingus website, as details on these may be updated often.
An Aer Lingus spokesperson said: "All impacted customers are being contacted directly and offered details of an alternative flight where feasible. All impacted customers also have the option of a full refund.
"Aer Lingus wishes to apologise to Aer Lingus Regional customers who have been affected by Stobart Air ceasing operations."
However, any Aer Lingus refund would be for the flight only, not for other parts of a holiday such as hotels or activities.
Most of the flights affected are domestic and run within the UK and Ireland, and may not involve a holiday.
But if they do, most travel insurance policies will pay out for other holiday expenses where a flight is cancelled.
These include activities you have already paid for, or are due to pay.
But insurers will expect you to have tried all other ways to get your money back before they step in.
Fiona Macrae, head of awareness initiative at the Travel Insurance Explained website, said: “Most hotel and accommodation providers have strict cancellation policies but may offer to reimburse costs or move the booking due to these issues.
"However, a refund or change of dates is not guaranteed and will vary between accommodation providers."
If customers cannot get these refunds, if the accommodation cost more than £100 and was booked with a credit card another option is available.
Passengers may be able to claim back these costs from their credit card provider under Section 75 of the Consumer Credit Act.
Anyone who booked with a debit card may also be able to recover these costs through their bank under the chargeback scheme.
It is worth checking the wording of your policy before you make an insurance claim.
These differ in terms of what they cover, and how much insurers will pay for certain claims.
Calling your insurer is wise if you cannot work it out.
A statement from Stobart Air said: “It is with great regret and sadness that Stobart Air can confirm that the board is in the process of appointing a liquidator to the business and the airline is to cease operations with immediate effect."
Around 480 staff are affected.
