Every figure above stays free, for any number of flights. $60 once · one licence key per person or team seat · 7-day full refund. AirHelp keeps 35% of whatever it recovers (50% once a case goes to court); Flightright quotes 20-30% plus VAT.
Article 7 band picker Sorts the flight into the €250 / €400 / €600 band and applies the intra-EU rule that caps every intra-EU flight over 1,500 km at €400, whatever the distance.
Article 7(2) halving test Halves the amount only when re-routing was accepted and the arrival delay stayed under 2 h, 3 h or 4 h for that band — the step hand calculations and chatbots apply to the wrong band.
National filing deadline, printed as a date Regulation 261/2004 sets no time limit at all: the window is national law and runs from 1 to 10 years (source: europa.eu Your Europe air passenger rights, plus the country tables at flight-delayed.com and skyrefund.com; Germany counts 3 years to 31 December of the third year). You get a date, not a vague window.
Agency cut beside your net Puts the no-win-no-fee commission next to what is left: AirHelp 35% of the recovery, 50% if it goes to court; Flightright 20-30% plus VAT. The percentage is an input so you can check the quote you were actually given.
Whole booking, not one seat Compensation under Article 7 is per passenger, so the popup totals the party on the booking and the .csv export lists every figure the airline will ask you to justify.
The default case, already filled in Opens on a real case so nothing is blank: 3,800 km, arrival 3 h 30 late, 2 passengers, no re-routing, flown 11 April 2026, claim in Germany, agency commission 35%. It answers €600 per passenger, €1,200 for the booking, €420 kept by the agency, €780 left for you, and file by 31 December 2029.

Arrival delay in — Article 7 band, party total and the filing deadline date out, for the traveller who keeps the whole payout.
AirHelp keeps 35% of whatever it recovers (50% once a case goes to court); Flightright quotes 20-30% plus VAT. On a two-passenger Band C delay that is €420 of €1,200.
What does the Flight Delay Claim Calculator actually work out?
It turns one disrupted flight into four numbers: the Article 7 band (€250, €400 or €600), the amount per passenger after the Article 7(2) halving test, the total for everyone on the booking, and the last date on which that claim can still be filed under the national law you choose.
Who is it for?
EU and UK business travellers, freelancers who fly to clients, and the office managers who book them — people holding a boarding pass and a three-hour delay who intend to claim themselves rather than sign 35% away to AirHelp, Flightright or Skycop.
Why will a free chatbot not do this?
Ask any chatbot how long you have to claim and it gives one number. There is no single number: Regulation 261/2004 sets no limitation period, so the window is national law and runs from one year to ten. It also routinely halves the wrong band and forgets that intra-EU flights over 1,500 km stop at €400.
What is free and what needs the key?
Every calculation is free, for unlimited flights, with no watermark and no lockout: band, per-passenger amount, booking total, agency commission and deadline date. The $60 key is for keeping and repeating — exporting the claim record as .csv and setting alarms 30, 14 and 1 day before the deadline.
What would paying someone else cost?
AirHelp keeps 35% of whatever it recovers and 50% once a case goes to court; Flightright quotes 20-30% plus VAT. On a two-passenger Band C delay worth €1,200 that commission is €420 — about fourteen times the price of this key, on one trip.
