What if I cannot find the airline's official claim form?

Use the carrier's official contact or complaints hub, state the remedy requested and ask for the correct form. Keep a dated copy and reference number.

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.
