Sources and method

How the checker decides

1. Scope. From your airports and the airline that operated the flight, it decides which of EU261, UK261, APPR and US rules apply.
2. Distance. Great-circle distance between your first departure and final destination airports, using coordinates from OurAirports (public domain). Distances within 15 km of a band edge are flagged.
3. Delay. Your scheduled and actual arrival times at the final destination, as you enter them in local time. We convert them using the airport's time zone, so delays that cross a clock change are counted in real time.
4. Rules. Thresholds and amounts come from one configuration file, dated and reviewed monthly. EU flights from 23 October 2027 use Regulation 2026/2202.
5. Reason. If you tell us the airline's reason, we apply the case law on extraordinary circumstances (EU/UK) or APPR's control categories (Canada).

The rules engine is checked against a test suite of more than 80 cases taken from the regulations, regulator guidance and CJEU rulings, re-run every quarter.

Known limits

• We rely on the times you enter. We do not use flight-tracking data.
• Connecting journeys are judged from origin to final destination and only if on one booking. Mixed cases (for example a non-EU first leg into an EU connection) can be more complex.
• EU limitation periods vary by country and have no official table. Several are disputed; we show the range.
• Gibraltar, the Channel Islands, the Isle of Man, the Faroe Islands and Greenland are shown as unclear.
• For a cancellation, we assume the 14-day, 7-day and 1-hour/2-hour windows as you describe them; the airline's records may differ.
• For a cancellation after which you took a refund, EU/UK rules still look at the replacement flight you were offered.
• Canada's proposed APPR amendments were not in force when checked. If they are adopted, the logic must be updated.
• Reg 2026/2202 brought-forward departure reductions (amended Art 7(3)) are not modelled.
