Flying Schengen-ZRH-NRT with 50 min connection in F.
So I arrive in A and head over to the F lounge. The First lounge is in the same "complex" as the Senator and Business lounge? #2 on this map.

Then there is passport control and a shuttle to E gates from the F lounge? If I am very late they might have a vehicle at my arriving flight?
