Not particular to any airport or any addon aircraft.
Any time you fly from/to a non-handmade (and non-addon) airport it seems to have some kind of “memory leak-like” behaviour. Like, if you saw too many jetways in your session, the jetways you see later will have a section missing.
For example I takeoff from RCTP (an international airport with dozens of jetways), sometimes the jetways further from my spawn point already have a part missing. If I then fly to another non-handmade/addon airport, usually the jetways there will have a section missing, too.
