What fees should I check before using a claim agency?

Compare the fee percentage, VAT, litigation or withdrawal charges, payment timing and the agency's authority. You can first use the airline's official free channel.

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.
