I want to complain about my delayed flight, can you help?
There's a template letter you can download and send to your travel company or airline directly, available on the CAA website.
Once you've complained to your airline, if you're not happy with their response the Civil Aviation Authority (CAA) may be able to help as it is responsible for regulating aviation in the UK.
You can get more information from the CAA website or alternatively phone their consumer advice line on 020 7453 6350.
