I think I remember my last visit at the T2 SQ FCL (must have been 7 or 8 years ago): At 10:30 PM the warm buffet was cleared and there was no bartender anymore, there were only a handful of pax left for the LH flight to FRA and the LX flight to ZRH. And there are no naprooms in the T2 lounge, right?
Alternatively, I could book an extra night in my hotel and then checkout at 11:00 PM. I decided to do this in Nov 2021, when LX177 was delayed to 1:30 AM. This was due to crew rest time issues, crew arrived early morning on LX176, then was in hotel quarantine and had to depart same night. Was impressed that I received a personal call from the LX Office in Zurich in the morning announcing the foreseeable delay, as LX176 had arrived late.
