Flying to HKG and BOM from LAS for leisure (Y) in November.
I'm AA PLAT with 150,00 AAdvantage miles and CX Green with 40,000 miles.
My plan was to fly LAS-LAX-HKG-BOM-HKG-LAX-LAS and try to upgrade to J LAX-HKG (I'm sure I'll sleep like a baby in Y on the way back).
I definetely want to FLY OW so I can reach Platinum this year (at 30,000 year-to-date).

1)Any ideas on where to find good fares apart from the usual suspects like the websites?
2)I understand the BOM-HKG leaves at an ungodly hour so any other OW options?
3)Any advantage to fly via YVR or San Fran instead of LAX?
4)Anything else I'm missing?

Thx!
