There is an underlying I class fare INX08DN1 for the 2392 price. Can be on either JL or AA metal across the pacific. Taking the AA 77W is a decent option as you can SWU yourself in to F really easily on LAX-HKG.
DAY/TIME PERMITTED MON THROUGH THU ON EACH TRANSPACIFIC SECTOR.
The AAvacations route does indeed get you a few hundred off, which you can spend $129 of the savings on a predeparture waiver and convert this well-priced nonrefundable fare into a refundable one ;-)
By the way, those $1200 ex-China fares were just the first crack in premium cabin performance for AA. $2k ex-USA fares to deep SE Asia are a big indicator that AA on other Asia routes as well.
