Will be returning from HKG to LAX on April 14th,2017.

Right now, the plan is to fly coach with Cathay or AA via (Avios) but I was hoping to fly business class. Is there any options available for me?

The only thing that i can think of now is United (80k each) or Korean Air (62.5)

-United is via Eva Air. Is this better than Korean air in terms of quality? The points difference is obvious and both required a layover anyways.

Am I missing anything else?

Total passenger:4

Will be using miles for the return trip.

Thanks all!
