What documents support a flight compensation claim?

Start with the ticket, original and changed itinerary, disruption notice, actual arrival, carrier reason and prior claim number. Add itemized receipts for expenses.

What to check

Keep the first claim, case number, airline reply, and any new evidence together. That makes it easier to ask a focused follow-up question or use the right complaint channel.

What to do next

Use the appeal guide to answer the airline’s actual reason, not just repeat the original request.
