I was due to depart HKG on Sunday, but UA has now cancelled all 4 flights arriving Saturday and leaving Sunday (EWR, ORD, SFO, and GUM). I have to say though, a supervisor at the 1K desk went above and beyond to get us reaccommodated with minimal disruption to our schedule, there are definitely still some gems working there. It's not the first time they've pulled strings for me on weather related delays/cancellations and moved a mountain, per se.
I've been watching the HKG airport site for cancellations, so far UA, TG, and QF have cancelled Saturday arrivals, and KL, LY have cancelled Sunday arrivals. Naturally both airlines from the Philippines have cancelled as well and looks like some regional carriers are starting. I don't expect much to be happening at HKG from late Saturday into Sunday night. Hopefully it doesn't flood as bad as KIX did last week during our last typhoon.
