Hello, I could not understand why every time I use Air China in China I get the Cathay Pacific catering vehicle?
As explained on the manual, and too many times to count on the forum, the livery you fly with your plane doesn't have any relationship with the livery of the ground operators, and this is of course correct, because it would be unrealistic to be serviced by your own company everywhere you go.
The operator is related only to the airport and the parking codes in the AFCAD.
