BKK: I just head to the 'newer' Priority Pass lounge (Louis Tavern?) that is a bit beyond the CX/BA lounges in that order on concourse G (i think). Much nicer, practically empty each time i've been there, very fast wifi, and okay-ish food.

SIN: The QF lounge is pretty decent, though i think that the FC section will be closing down in due course. Also within the skyview lounge, the 'additional seating' section up a small flight of steps is, relatively, much nicer and quieter than the general area.
