It doesn't really matter they don't have F section in SYD Air NZ Koru lounge. It is still a pretty decent lounge and one can take a shower to freshen up, eat a little something before going to board. Although arrival in BKK around 3am is a little annoying. But on the bright side (if u stay in BKK for a stopover holiday) U have no traffic going to town and can hit the bed for a good sleep. A little problematic if u are transferring to onward flights. I was told by staffs at F lounge that they will set u up in the Royal silk lounge first. Come 5 am, u can move back to F lounge. TG won't abandon F passengers just like that.
