When must I send a flight compensation claim?

Deadlines vary by jurisdiction and claim type. For Canada APPR fixed compensation, the usual written request window is one year; check other rules separately.

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.
