Which airlines route should I use?

Use the airline route when the problem is with the flight, baggage handling, denied boarding or the airline refund decision. Use a travel booking route instead if the dispute is mainly with an agent or package provider.

Useful contextAirline complaints often turn on flight number, route, delay length, cancellation reason, baggage evidence and what the airline has already offered.
Avoid this mistakeDo not mix separate trips, passengers or bookings unless the same failure affected all of them.

How to structure a airlines complaint letter

Start with a concise summary of what happened, then set out the key dates, references and evidence. Keep the tone calm and factual. A business can respond more easily when the letter separates the problem, the impact and the outcome requested.

If the airline does not resolve the complaint, the route may involve its approved ADR scheme or the Civil Aviation Authority route where applicable.

ClearComplaint uses this sector context to guide the letter structure, but you should always review and edit the final wording before sending it.
