Flight delay compensation calculator

Pick the airports, the airline that operated the flight and what happened. The result sits in the address, so a copied link opens the same answer.

Updated

Where the trip started. For one booking with connections, the first airport.

Where the trip ended: the final destination.

The operating airline, not the one on the ticket. A boarding pass or the flight status page names it.

What happened

At the final destination, when the aircraft door opened.

We read this to explain the result. We never decide whether it counts as extraordinary.

Carried into the claim letter. It does not change the amount.

Choose where the trip started, where it ended, the airline and what happened. The result updates as you type.

How the calculator decides

  1. It measures the great circle distance between the two airports.
  2. It checks each rule set against the departure airport, the arrival airport and the airline’s license. See rules.
  3. It tests the delay (3 hours or more at the final destination) or the cancellation notice.
  4. It reads the reason you give. It never decides whether circumstances were extraordinary.

Questions about the calculator

Which airline should be selected?
The airline that operated the flight, not the one that sold the ticket. On a codeshare or a wet lease the boarding pass or the flight status page names the operating airline.
What goes in for a trip with a connection?
On one booking, enter the first departure airport and the final arrival airport, and the operating airline of the delayed leg. See connecting flights.
Can the result be shared or printed?
Yes. Your inputs live in the page address, so a copied link opens the same result. Use the print button for a paper copy.
Are the flight details sent anywhere?
No. The calculation runs in your browser. We record only coarse ranges, never the airports, the flight number or the date.
Does Hours Late decide whether the airline owes you?
No. It shows what the rules say on the details you enter. The airline decides first and, if you disagree, a national body or a court decides.

Information, not advice

Hours Late is not a law firm and not a claims company. It does not file claims for you. The results are estimates from published rules and the details you enter. They are not legal advice. Airlines and courts decide each case.
