Agree with FLL. July and August are always horrible for fares, lots of TPAC traffic in both directions. It isn't any better from other Asian stations. I'm talking about Y class, can't even begin to fathom C and F pricing. Y availability is not great at least for first half of August, either.
I've noticed in the last 2 years, on paid tickets sometimes it makes sense to route via Europe (selected locations). Especially if heading to the eastern part of USA. It was uniformly way more expensive than TPAC routings--now it's more competitive, so that might be an option for some.
