Travelling business class , swiss Air, I am arriving in ZRH from HK non schengen E gates, travelling to Moscow which I am told is D gates not E. I have 6 hours transit. I wish to utilise the business lounge and not sure of how to get there. Do I exit tfrom arrival at E gates thru passport control...

So if I arrive from HK in transit on way to Russia, I have to exit thru passport control to get to gate E business lounge? And then return thru incoming passport control? I have a 6 hour layover. Is it correct returning Prague to to Zurich outbound to HK it is easier to access E lounges.
