AirHelp Review: What to Check Before You Sign the Assignment Agreement

What AirHelp Actually Does

AirHelp is a claims-management service for flight delays, cancellations, overbooking, and missed connections. If your flight was disrupted and you think you're owed compensation under rules like EU261 (Europe) or similar passenger-rights schemes elsewhere, AirHelp checks your eligibility, builds the case, and handles the airline's correspondence. Like most services in this category, unresolved claims may be escalated further -- arbitration or legal action -- if the airline keeps refusing payment.

The model is "no-win, no-fee": no upfront cost, and AirHelp keeps a cut of the payout only if the claim succeeds. That's why services like this exist -- most travelers won't spend hours escalating a small claim to a national enforcement body themselves.

The part that trips people up isn't the fee -- it's the paperwork you sign to get started, specifically the Assignment Agreement. (Our travel tools directory covers booking, insurance, and claims services in one place.)

What the Assignment Agreement Actually Does

When you submit a claim through AirHelp, at some point in the process you're asked to accept an Assignment Agreement. This is not just a "we're now working on your case" formality. Legally, it transfers your claim -- your right to pursue compensation from the airline -- to AirHelp, which then pursues it in its own name (or through its legal partners), not as your representative on a claim you still own.

That distinction matters for two practical reasons:

• You're not just hiring help -- you're handing over ownership of the claim. Once the assignment is in effect, the claim itself belongs to AirHelp (subject to your right to a payout under the agreement's terms), not to you personally.
• It can affect what you're able to do in parallel. If a claim has already been assigned, most airlines and enforcement bodies won't process a second submission from you directly for the same flight while AirHelp's claim is active, because the right to pursue it is no longer yours to exercise.

None of this makes the arrangement unreasonable -- assignment is a standard legal mechanism used across claims-management and litigation-funding businesses. But it's worth reading as an assignment, not skimming it as a checkbox, since it decides who controls the claim once you've filed it.

A Checklist Before You Sign

These are the things worth confirming for your own situation before you accept the agreement, not after.

1. How the success fee is structured

AirHelp charges a percentage-based success fee taken from the compensation if the claim succeeds, and an additional charge may apply if the case goes through arbitration or court rather than being resolved directly with the airline. The exact percentage and any surcharge can vary by case type and country. Check the fee schedule shown to you at submission, and weigh it against what filing yourself would cost you in time.

2. What happens if the airline doesn't pay voluntarily

A meaningful share of EU261-type claims aren't settled by the airline on the first request -- they get contested, delayed, or ignored until pressure escalates. Confirm whether escalation to arbitration or legal action is included in the fee you agreed to, or whether it triggers an extra cost. This is where "no-win, no-fee" gets tested: it protects you from losing money, but not from a smaller share of a win if the case drags out.

3. Assignment Agreement vs. Authority Document -- these are not the same thing

Depending on jurisdiction, some claims processes distinguish between an assignment (you transfer ownership of the claim) and an authority document or power of attorney (you keep ownership but authorize someone to act on your behalf). The consequences differ -- an authority document generally leaves you free to withdraw and pursue the claim yourself down the line; a completed assignment generally does not, since the claim is no longer legally yours to pursue. Read which one you're actually being asked to sign rather than assuming they're interchangeable, since the label can vary by country and by which document is presented in your flow.

4. Whether you can still deal with the airline directly afterward

Once a claim is assigned, contacting the airline yourself generally won't help -- its obligation now runs to whoever holds the claim. If you want to keep the option of negotiating directly, confirm before signing whether the document is an assignment or something narrower.

5. Whether there's a withdrawal or cooling-off period

Consumer contracts in a number of jurisdictions include a short window during which you can cancel without penalty, though the length varies and we haven't verified it against AirHelp's specific current terms. Confirm whether it applies, and what the deadline and process are, against the terms shown at signup.

6. What happens to the claim if you do withdraw

If you cancel within any applicable window, check whether the claim reverts to you so you can pursue it yourself or through another service, or whether withdrawal just ends AirHelp's involvement without returning anything in progress. Easier to check before signing than to sort out after.

Why the Same Service Can Feel Very Different Depending on Your Claim

How an assignment-based service like AirHelp feels comes down largely to what kind of claim you have. A clear, well-documented delay is the case it processes fastest. A claim the airline contests -- citing "extraordinary circumstances," for instance -- takes longer and involves more escalation, which is also where the fee draws the most scrutiny relative to the payout.

When AirHelp Is a Reasonable Choice -- and When Filing Yourself Makes More Sense

AirHelp tends to make sense if any of these apply to you:

• You don't have time to track correspondence with an airline over weeks or months, or you're not confident navigating the applicable passenger-rights framework yourself.
• Your claim looks likely to be contested rather than accepted outright, and you'd rather have someone experienced handle the escalation than do it yourself.
• You're filing from outside the country where the airline is based and don't want to deal with the language or procedural differences of escalating there.

Filing directly with the airline (or the relevant national enforcement body) tends to make more sense if:

• The delay or cancellation is clear-cut and well-documented -- you're confident the airline will pay once you ask, and you'd rather keep the full compensation than give up a percentage.
• You have time to follow up over several weeks and don't mind escalating yourself if the first response is a denial.
• You want to retain full control of the claim rather than assign it -- for instance, because you might want to negotiate a specific remedy (like rebooking terms) alongside the cash compensation.

Some travelers split the difference: try a direct request to the airline first, and only bring in a service like AirHelp if that's denied or ignored. It costs a little time up front but avoids assigning over a claim the airline might have simply paid on request. See how Compensair structures the same type of claim before you commit to either.

FAQ

Does AirHelp charge anything if my claim doesn't succeed?

The core model is no-win, no-fee for the claim itself, meaning you generally don't pay AirHelp if the claim is unsuccessful. Always confirm the current fee terms shown to you at submission, since specific conditions can change.

Can I cancel after I've submitted a claim?

Most consumer-facing claims services offer some form of cancellation window, but the deadline and process should be checked against the terms shown at signup rather than assumed.

Is signing the Assignment Agreement the same as hiring a lawyer?

No. It's a transfer of the claim to AirHelp (or its legal partners), a different relationship than retaining a lawyer while you keep ownership. Services in this category typically route legal escalation through partner law firms rather than requiring you to appear personally.

What if I already contacted the airline myself before using AirHelp?

That doesn't usually disqualify you from using a claims service, but mention it when you submit if the airline already agreed to pay -- it affects how the claim should be handled.

Bottom Line

AirHelp isn't complicated to use -- submit flight details, sign the agreement, and let someone else handle the airline. What's worth slowing down for is the signature: an assignment agreement moves ownership of your claim, not just paperwork, so read carefully, confirm the fee structure, and check the cancellation terms before you accept. A clean, undisputed delay is worth trying yourself first, to keep the full payout. A contested one is what the service is built for.
