Can I claim without a flight-delay certificate?

Often you can begin with notices, boarding records and actual-time evidence. Ask the airline for a certificate if an insurer or claim process requires one.

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.
