ClaimFlights review

ClaimFlights has the lowest headline fee we found: its homepage states a 25% success fee on a no win, no fee basis. Its own comparison table shows €420 paid out on a €600 claim, although that table dates from August 2021 and appears to reflect different fee assumptions. The service covers EU261 claims for delays, cancellations, overbooking and denied boarding, with airline pages for Ryanair, easyJet, British Airways and others. The trade-off is transparency. The site does not say whether VAT is added to the 25%, does not publish a separate legal action fee, and gives far less detail on its company, court record and payout process than AirHelp, AirAdvisor or Flightright. It is a reasonable option if the fee matters most and your claim is simple. Read the terms before you sign so you know the full deduction if the case goes to court.
