LAX is a terrible connection and a bunch of overflying. Look north to YVR, it's an easy drive, especially if you have a NEXUS card.
MU ILX0ZYRN is pricing to about US$2100 and isn't bad with the connection in PVG. No idea when you want to travel, there are some blackout dates for this fare.
There are also one stop flights from YVR to BKK in the $2k range and it's under $100 for a RT BKK-HKT ticket. BKK is a fun city, I'd go there en route to HKT, which in my opinion is maybe a nice beach but you're missing the experience of Bangkok.
If you are interested in Prem Y, there are a number of decent options. $1300ish for YVR-HKT and $1000ish for YVR-BKK
