Over the weekend, hundreds of flights from Manchester Airport were cancelled due to a major power cut.
Passengers flying from Terminals 1 and 2 were told not to go to the airport, while those already inside faced huge delays.
Flights finally started departing this morning, but what are your rights if yours has been cancelled?
Watch: Travel disruption after Manchester Airport power cut
Here’s what you need to know
Your flight is covered by UK law if it departs from a UK airport, arrives at a UK airport on a UK or EU airline, or arrives at an EU airport on a UK airline.
Under UK law, if your flight is cancelled, the airline must either give you a refund or book you on an alternative flight – either with them or a rival airline.
It is up to you whether you still want to travel at that time – or reschedule your holiday for a later date.
If another airline is flying “significantly sooner” than yours is able to offer, you may have the right to be booked onto a rival flight, but this has to be negotiated with the company.
What are the airline’s policies?
As well as being covered under UK aviation law, each airline has its own cancellation policy for customers.
EasyJet allows customers to either switch to another flight for free, choose a voucher for the full value of the booking, or request a refund.
Ryanair passengers can either claim a full refund or change to an alternative flight, while TUI passengers with cancelled flights should receive a full refund within 14 days – and you may also be entitled to compensation.
British Airways passengers are offered a full refund, while Wizz Air allows passengers to request a refund or rebook onto the next available flight.
If you have booked through a tour operator or travel agent, they will have their own policies.
What if you’ve booked a package holiday?
If your flight is cancelled, and you’ve booked a package holiday, you have the same rights as any other passenger, according to trade association ABTA.
You also have additional rights regarding the rest of your holiday.
Typically, your travel company will contact you in advance to re-arrange your flights.
But, if you’re at the airport when the flight is cancelled, you should contact your travel company to talk through your options, ABTA said.
If your flight can’t be rearranged and your holiday has to be cancelled, or new arrangements are made that result in a significant change to your holiday, then the travel company must offer an alternative holiday if they can.
If not, they must offer a refund of the full package price, not just the flight part.
Generally, a change of more than 12 hours on a 14-night holiday is considered a significant change.
