I was just browsing the flight paths when I saw this:
(FlightRadar24: SN2825 from BRU to BUD on 26 Jul 2022)
But normally the path is straighter like this (not flying over Zurich):
(FlightRadar24: SN2825 from BRU to BUD on 25 Jul 2022)
I have seen even more deviation, like flying above Venice. This all adds some time to the total flight time.
Why is that? How can I know the reason?
