Hi Umberto,
I think I was contacting you about this a while back, and since then, this topic has vanished somehow, so I'd like to reopen it.
Prague Airport doesn't have 'its own' handling with the logo of the Prague airport. Instead, there are two agencies doing the handling.
Menzies and Czech Airlines Handling
Since you have Menzies already implemented, I will send a link to the Czech Airlines Handling only.
https://www.czechairlineshandling.com/enWould it be possible to add Menzies as an operator for Prague, and, if possible, add Czech Airlines Handling?
Many thanks!
