Everything you need to know if your flight is disrupted

Some flights at Heathrow have resumed after the airport was shut on Friday due to a fire at a nearby electrical substation that supplies it with power.
The UK’s busiest airport has warned of significant disruption over the coming days, with at least 1,300 flights in and out cancelled.
What are your rights if your journey has been disrupted and can you get your money back?
Do not attempt to travel to the airport, but keep in touch with your airline who will be able to advise you about refunds or booking alternative flights.
If your flight is covered by UK law, your airline must let you choose between either getting a refund or being booked on to an alternative flight.
