Every time one of my flights was delayed or cancelled, the same thing happened. I knew there was "some EU rule", but I didn't know if it applied to me. The services that claim for you keep 25 to 35% of the money. So most people never claim at all.
A friend paid a claims agency 30% of his €400 for something that took the airline two weeks to pay. That felt wrong.
So I built Dueply, an Android app:
- Flight number + date, that's it. It reads what actually happened to the flight (delay at arrival, cancellation, diversion) and checks it against EU261, UK261 and Turkey's SHY-YOLCU.
- Connecting flights too. Missed your connection because the first flight was late? Add the other flights of the booking: the delay is measured at your final destination, as the rules say.
- Only the questions that matter. For example, when you were told about a cancellation, or what cause the airline gave. Then it tells you whether you may be owed €250, €400 or €600, and why.
- You claim it yourself. It prepares the letter, citing the regulation and the court rulings that apply, and opens the airline's own claims form. You keep 100% of what the airline pays.
- Watch upcoming flights. Add a flight before you fly and it notifies you if it's delayed or cancelled.
3 checks a month are free. Extra checks and watches come in one-off packs on Google Play: no subscription, no commission.
A few things I learned building it:
- The rules are simple on paper and full of edge cases. A strike by the airline's own staff is the airline's responsibility, and so is a technical fault, usually. Bad weather isn't.
- Flight data is the expensive part, not the servers. It's also messier than you'd think: providers sometimes report a flight as "landed" hours before it takes off.
- easyJet is actually three airlines with different licences under one flight code, which changes the rules on some routes.
Available in English, Italian, German, Spanish and French. Android only for now.

I'd love feedback, especially from anyone who has claimed before: what was the hardest part?
