FFCheck vs Compensair — what you actually keep

Compensair is a European claim service with a "no win, no fee" model: you assign your claim right via a signed "Assignment of Rights", they pursue the claim, and on success retain 25% of the payout.

The math on a €400 EU 261 claim:

• FFCheck: €9.99 for the letter, you get €400 direct from the airline. Net: €390.01.
• Compensair: €0 upfront, 25% commission retained: €100. Net: €300.

Difference: €90 per claim. On a family of 4 (€1,600): FFCheck €1,590 vs Compensair €1,200. Difference: €390. On a €600 claim: FFCheck €590 vs Compensair €450 (difference €140); family of 4 on €2,400: FFCheck €2,390 vs Compensair €1,800 (difference €590).

Time. Compensair: 8-12 weeks per their FAQ. FFCheck: PDF in seconds, airline 14-day deadline (as our letter demands).

Data. Compensair "Assignment of Rights" covers: ID copy, boarding pass, booking PNR, the IBAN THEY receive on, contact details. Privacy statement mentions aggregation + sharing with "trusted partners". FFCheck: only what you type + Stripe token. No Assignment, no ID copy, no IBAN.

"No win no fee" — the asterisk. Compensair's no-fee clause covers only the basic process. If court action needed: often a surcharge OR they choose not to pursue (since their 25% of €0 = €0 doesn't cover costs). You lose control plus time.

When is Compensair still better? Honestly: for highly contested cases where you have no time for escalation and are willing to give up 25% for "hands-off" service. For typical EU 261 delays: no.
