My scenario is: We all arrive in Blue1 ticketed business class to ZRH around noon and continue to LX180 to BKK in the evening (two *G pax in F, and 2 non-status pax in C).
I guess on arrival we all can use the Arrival lounge, but in the evening when we get back to the airport from town, according to the rules only 2 of us who fly in F can use the the First Class lounge, right? But what do you think, is it worth asking if the other two who fly in C on the same flight could join us -or are they very strict with the rules?
