Firstly, many thanks for reading this thread -- I greatly appreciate it.

Would anyone know the answer to this at Zurich Airport? Is it possible to walk from the business lounge in the A gates area to the business lounge in the E gates area, and then walk back again to the A gates area?

Basically, I am flying on Swiss in business next month from Zurich to London, and I suspect that most people would use the business lounge at the A gates area (Schengen). However, I will have several hours to kill on the day of departure and rather fancied trying the business lounge in the E gates area (non-Schengen), but I don't know if I would encounter any issues with security, etc., when trying to traverse the Schengen/non-Schengen area -- to get to the lounge at the E gates area, I mean -- and then, once again, when returning to the Schengen area before taking my flight to London?

Any experience of doing this, or any advice at all, would be much appreciated.

All the best
