Too much a/c in the Clubhouse? I'd have been thrilled a few weeks ago when my maiden SQ voyage (in F, and inspired in part by your RTW report, btw) left from a T4 with NO A/C. None! Lounge experience was def affected, though what can you do but make the best of it
As long as SQ checkin & gates are alongside the likes of PIA, there is likely to be a perception (rightly or not) of a "third world experience". There was a procession of Pakistani "diplomats" who kept trooping past us in the F security line, straight to the front. Probably doubled the wait time
Not exactly sure what SQ can do, as the facility itself seemed decently nice. (Maybe rent space alongside BA/UA in T7?)
I had no problems with gate lice as I positioned myself just by the F sign and was second aboard after the numerous pre-boards :-)
And yes, it was great once on the plane
