Greetings,
Several pilots informed me that there's an offset between the Online and Offline timetable flight numbers. For example, flight LFST-LSZH is listed as 1469 in the Offline timetable and as 1471 in the Online one.
This is because the Offline timetable wasn't updated (it will be soon). Please be aware of this bug when you use it, and always check the flight number in the Online timetable too when filing a pilot report.
