What are my rights if my flight is cancelled or delayed?
Flights are cancelled owing to air traffic control problems, so what are your rights if you're affected?

Thousands of air passengers have seen their travel plans disrupted after an air traffic control problem grounded nearly 2,000 flights across the UK.
When a flight is cancelled or delayed, passengers affected have various rights – such as a refund or be put on another flight. However, these can vary depending on which carrier you are flying with and from where.

If your flight was coming into the UK on a non-UK or EU airline, then you should check the terms and conditions of your booking.
