AirAdvisor charges 30% on flight claims and names no separate court fee, though it does not say whether VAT is included; ClaimFlights charges a flat 25% plus VAT, the same in court, bearing court and lawyer costs. AirAdvisor's Trustpilot rating is 4.3 out of 5 from 2,603 reviews, ClaimFlights' 4.2 from 501.
AirAdvisor vs ClaimFlights: which should I choose?
ClaimFlights suits a claimant who expects the airline to fight, since its fee does not rise in court, or who lives outside the EU and pays no VAT on it. AirAdvisor suits one with a baggage claim or a claim under Canadian or Turkish rules, which ClaimFlights does not name among the claims it pursues.

Neither paid to be on this page. The page does not score them: it says which suits whom.
AirAdvisor: 30% on flight claims, 40% on baggage.
ClaimFlights: The same flat 25% fee in court.
