How much you can get
There is no cash compensation for delays in the US. Since October 2024, if your flight is cancelled or significantly changed (3+ hours domestic, 6+ hours international, a different airport or more connections) and you choose not to travel, the airline must refund you automatically, in cash.
If you are bumped against your will from an oversold flight leaving the US: nothing if the airline gets you to your destination within 1 hour of the original arrival; 200% of your one-way fare if you arrive 1–2 hours late (1–4 hours on international flights); 400% if later — both up to caps set by DOT. These bumping rules don’t cover flights to the US from abroad.

How to claim it yourself
Ask the airline for a refund to your original form of payment. If it refuses, file a complaint with the US Department of Transportation.
The claim services we work with (AirHelp, Compensair) take EU and UK cases. Under these rules you claim from the airline directly, which is free.
