My problem shows up when I buy a flight with a codeshare number.
Real example I experienced last week. Lufthansa sold me a ticket for a flight from Munich to Zurich. The flight was operated by Swiss with real flight number LX1109. In my reservation, there was codeshare number LH5786 and this number was downloaded to App in the Air application. Even in the statistics app shows this flight as Lufthansa flight.
Could you consider to show real flight number in the application?
