Flowchart​

Allows you to offer passengers compensation services when their flight is delayed. Because the service is tied to a specific flight, the flow requires a flight number and departure date — these can either be provided upfront or looked up via getFlights when only a route is known. Once a matching product is found, an order is placed and a voucher is delivered to the passenger.

Delay Care Search and Booking Flow​

This scenario describes the interaction flow between the client and the ETT API via the WebApp for searching, selecting, and booking Delay Care services, as well as retrieving a voucher.

  3. (Optional) Retrieve flights for a specific route
