HUNDREDS of Brits saw their travel plans plunged into chaos after a tech glitch yesterday - here’s what to do if your flight was affected.
If your trip was delayed or cancelled, you could be entitled to compensation.

Under UK law, airlines have to provide compensation if your flight arrives at its destination more than three hours late.
If you’re flying to or from the UK, your airline must let you choose a refund or an alternative flight.
You will be able to get your money back for the part of your ticket that you haven’t used yet.
So if you booked a return flight and the outbound leg is cancelled, you can get the full cost of the return ticket refunded.
But if travelling is essential, then your airline has to find you an alternative flight.
This could even be with another airline.
However, the airline doesn’t have to give you a refund if the flight was cancelled due to reasons beyond their control, such as extreme weather.
Disruptions caused by things like extreme weather, airport or air traffic control employee strikes or other ‘extraordinary circumstances’ are not eligible for compensation.
Some airlines may stretch the definition of “extraordinary circumstances” but you can challenge them through the aviation regulator the Civil Aviation Authority (CAA).
If you can’t claim compensation directly through the airline, your travel insurance may refund you.
Policies vary so you should check the small print, but a delay of eight to 12 hours will normally mean you qualify for some money from your insurer.
Remember to get written confirmation of your delay from the airport as your insurer will need proof.
If your flight is cancelled entirely, you’re unlikely to be covered by your insurance.
This comes after
Most of these cancellations were at London Heathrow, with 29 departures and 17 arrivals.
A spokesperson for NATS said the issue was related to radar.
There is no evidence the disruption was down to a cyber incident, according to the official body.
NATS said in a statement: “This was a radar-related issue which was resolved by quickly switching to the back-up system during which time we reduced traffic to ensure safety.
“There is no evidence that this was cyber related.”
