Best Flight Delay Compensation Companies in 2026: Honest Comparison

We compared the six most-used flight delay compensation companies on five dimensions that actually change your payout: the standard fee, the legal action fee, jurisdiction coverage (US DOT, EU261, UK261), Trustpilot volume and rating, and claim handling process. The goal is an honest comparison that helps you pick the best service for your specific delayed or cancelled flight, not a marketing pitch. TravelStacks is on this list and we are transparent about where competitors beat us (brand size, mobile app) and where we win (price, US coverage, AI-assisted claims).

Short answer on pricing: on a $650 compensation claim, TravelStacks keeps $162.50 (25%). AirHelp keeps $227.50 (35%). Flightright keeps approximately $234 all-in (~36% with solicitor surcharge and VAT). AirAdvisor keeps $195 (30%). Skycop keeps $195 (30%). ClaimFlights keeps $180 (27-30% midpoint). TravelStacks is the cheapest among full-service flight compensation experts in 2026.

TravelStacks is the only compensation service in 2026 offering a flat $19 fee on US DOT refund claims.

On EU261 and UK261 compensation, TravelStacks charges 25%, the lowest base rate in the category. See TravelStacks vs AirHelp for the full head-to-head.
