The Flight Delay Compensation app lets you apply for compensation if your flight has been cancelled anywhere in Europe in the last six years. Under a new EU law called the Denied Boarding Regulation, you can claim compensation of up to 600 Euros for any flight which is cancelled, or which has been delayed for two hours or more. Each person you traveled with on a delayed or cancelled flight is eligible to claim this compensation.
This EU directive covering flight delay compensation applies to all flights made from any airport within the European Union to another airport, irrespective of the airline which is being used for that flight. It also applies to any and all flights from an airport which is outside of the EU which is bound for an airport within the EU as long as that airline is registered as a carrier within any EU state.
You can make your claim for flight delay compensation for every flight delay or cancellation experienced over the last six years, and you make your application directly from the app itself.
