Hi All...looking for some help with an upcoming trip on Jan 3 - Jan 10 2018.

I'd like to fly from LAX to HKG with a 1 stop max in business using my United and Chase points (that I've collected forever!). It looks like the best use of points is the 80k saver award booked round trip (160k total). I would have to use one of their partner airlines get this rate which include: Asiana, Air India, Thai Airways and Air China...Is using the United website the best way to book this flight? Has anyone had any experience/feedback on any of these flights in business to HKG?

I've been pretty good at accumulating points but feels like using them is also something to learn...First time booking an international business class flight using United points so any help would be appreciated! TIA!
