Who runs AirAdvisor
AirAdvisor’s imprint names two companies. AirAdvisor International Inc. is registered in the United States (registration number 7649235) with its registered office at 16192 Coastal Highway, Lewes, Delaware 19958. Air Advisor sp. z o.o. is registered in Kraków, Poland (KRS 0000672557, NIP PL9452207187). Its terms say you contract with one or the other; Delaware law applies unless you contract with the Polish company, when Polish law applies. The imprint lists Anton Radchenko, Esq. as founder, CEO and legal representative, states that AirAdvisor is “not a law firm” but works with licensed lawyers, and names Hiscox as its professional indemnity insurer.
What it does
According to its terms (clause 2.1), AirAdvisor pursues flight compensation under EC 261/2004, the UK’s retained version (UK261) and the laws of the USA, Canada, Turkey, Ukraine and other countries. It also handles baggage claims under the Montreal Convention and national law, and expense claims for accommodation, meals and transport after a disruption. It may decline claims it considers weak. The site is available in 23 language versions, including English (UK and US).
Fees
AirAdvisor’s price list gives:
- Flight compensation (EU261/UK261): 30% including VAT for claims resolved before court. Its own examples: €180 fee on €600 (you keep €420), £156 on £520 (you keep £364).
- Legal action: 50% “if your case requires legal action with external lawyers”. Its homepage FAQ mentions a grace period in which the fee stays at 30% if the airline pays quickly after legal action begins.
- Baggage and expense claims: 40% including VAT, with a flat €90 fee on payouts under €225 (£80 under £200). It says it never charges more than the airline pays.
Payouts are in euros by default; if you ask for another currency, exchange rates and charges follow AirAdvisor’s payment providers’ terms. You pay your own bank’s charges; the price list notes some banks may charge a €30 transfer duty. No admin fees are listed.
Legal action
Under its terms (clause 2.5), AirAdvisor decides independently whether to start litigation and instruct a third party; if it does, the 50% fee replaces the lower rate. The price list says AirAdvisor pays court fees, state duties and notary fees, and covers lawyer and bailiff fees where needed. If an original document must be sent to the airline, an authority or a court, you sign and send it at your own cost.
How a claim works and what you provide
- Check: enter your airports, airline, flight number and date in its instant flight check.
- Sign: accept the terms and sign an assignment of the claim (clause 1.5); you must give accurate information (clause 4.1).
- Handling: AirAdvisor contacts the airline and, if needed, instructs lawyers. A court may require further documents such as a notarised power of attorney.
- Payout: paid to the bank details in your member account.
If the airline pays you directly while AirAdvisor is actively handling the case, the payment counts as AirAdvisor’s result and its fee is due within 30 days (clause 5.1(c)). You can cancel within 14 days of submitting a case only if AirAdvisor has not yet filed it, and you must reimburse proven expenses.
Payment and timing
The homepage says claims usually take up to 6 weeks, or up to a year if the airline ignores or rejects the claim. The terms say payment is made within 30 days of receiving correct bank details (clause 3.4), and that if payment cannot be made, the funds become AirAdvisor’s property 180 days after the first notice to you (clause 3.5) – so keep your bank details up to date.
Notable facts
- The terms carry the dates 14 October 2017, 13 April 2021 and 1 September 2022, and say they can be amended at any time without notice.
- AirAdvisor publishes delay statistics, lawyer-reviewed guides and comparison pages against other claim companies, including AirHelp.
Trustpilot and other ratings
On 10 November 2026, Trustpilot’s profile for airadvisor.com showed a TrustScore of 4.2 from 2,618 reviews. AirAdvisor’s own homepage displays a Reviews.io rating of 4.5/5 from 28,798 reviews. Neither platform verifies the content of reviews.
Pros and cons
Pros
- 30% including VAT, below the 35% charged by AirHelp and Flight-Delayed
- Handles baggage and expense claims, not only EU261/UK261
- Clear worked examples in euros and pounds
- Covers court fees and lawyer costs
Cons
- 50% if external lawyers are needed

- Unclaimed payouts forfeited after 180 days

Who it suits
AirAdvisor may suit passengers who also have a baggage or expenses claim, or a claim under non-European rules, and want one company to handle it. For a plain EU261 or UK261 claim, its 30% is lower than several rivals, but it rises to 50% with external lawyers. Compare all providers in claim companies compared, or claim yourself.
What you keep on a €600 or £520 claim
Per passenger, for a successful claim on a long-distance flight (the top compensation band).
| Scenario | You keep of €600 | You keep of £520 |
|---|---|---|
| Standard (30%) | €420 | £364 |
| With external lawyers (50%) | €300 | £260 |
The standard figures are AirAdvisor’s own worked examples.
For comparison: if you claim yourself you keep the full €600 or £520. See every provider side by side in claim companies compared.
