Enter where you flew from and to, the airline, how late you arrived and the cause. The calculator shows the refund you're owed, any fixed compensation under EU, UK, Canadian and other rules, and what the cause changes. A domestic US flight carries a refund right and no cash compensation1.
Pick where you flew, the airline, how late you arrived and the cause the airline gave. The result lists every rule that applies, side by side. Nothing you choose leaves this page.
Five trips run through the calculator and the rules behind it.

Each rule read on the law or the regulator's page on 15 November 2026. Saudi Arabia is left out: its regulator's site did not answer on 15 November 2026 and the figures seen were search extracts only. Canadian amounts in the rules (sections 19 and 12) and the EU and UK amounts are read on the law; Israeli amounts are base figures from a commercial consolidation.
Next step: the claim page writes the letter. The rules in full are on the flight delay compensation and cancellation compensation pages.
Up to EUR 600 under EU261, GBP 520 under UK261 or CAD 1,000 in Canada when the airline caused it and you arrived late enough. US law pays no fixed sum for a delay.
US airlines pay no cash for a delay; their plans promise a meal voucher after 3 hours and a hotel overnight when they caused it. Fixed sums come from EU, UK and Canadian rules.
Not with a fixed sum under the US, EU, UK or Canadian rules. South Korea's standards give 10% of the fare from 2 hours.
3 hours late on arrival under the EU, UK and Canadian rules. In the US a 3 hour domestic or 6 hour international delay gives a refund right if you do not fly, and no payment on top.
Yes. It shows the refund threshold and no fixed sum, because US law has none, and points you to the airline's own promises.
Every figure links to its source. "Checked at source" means the law, the regulator's page or the airline's own page was read on or before 15 November 2026. "Reported elsewhere" means it came through another outlet, a search extract of the official page, or a figure worked out from project data. Sources that also feed the main page link to the methodology page.
