I'm curious if anyone has an official access rules list, similar to what exists for the LH arrivals lounge in FRA ( https://www.flyertalk.com/forum/luft...ge-fra-13.html ).

The reason I ask is: UA business flights apparently do get access to the ZRH arrivals lounge. And yet, many times I've shown my UA business arriving BP, and have been asked to show my (UA) *G card. Doesn't make any sense (unless they're actually just trying to get me to prove that I am who I am, but surely they'd ask for ID in that case).

// EDIT: and then I found this thread. UA*G apparently gets access (which would be great - does that work if I'm UA*G arriving on an LX short-haul too?), but still not clear why they don't just accept my UA J BP:
Why was I allowed into the Zurich Arrivals lounge with UA Star Gold ?
