This is a free reference for working out what an airline owes you when a flight goes wrong. It covers four regimes — EU261, UK261, Canada's APPR and the US DOT rules — and it tells you which one reaches your flight, what it pays, and the article it comes from.
Why it exists
The search results for this subject are dominated by claim companies, whose business model depends on you not discovering that a clear-cut claim takes one email. Their calculators are lead-capture forms: they ask for your details before telling you the number, and they do not mention the free routes. Several of them also quote amounts that are simply wrong, because a flat figure converts better than an accurate one.
So this site does the opposite. The number comes first, no email required, with the legal basis attached and a template letter so you can claim it yourself and keep all of it.
How it is funded
Advertising, and commission on some links to claim companies — paid out of the firm's fee rather than added to your claim. That is a conflict of interest and you should weigh it. We have tried to resolve it the honest way round: the guides are built to talk you out of needing a claim firm, and we say plainly when one is worth using and when it is not.
What this is not
It is not legal advice, and we are not a law firm or a claim company. We cannot take your claim on, and we have no relationship with any airline. If a figure here matters to a decision you are making, check it against the regulator we cite on that page.
