Hi. I'm hoping someone can give me some ideas on the below.

I am planning to fly to Bangkok from Tokyo and back.

Using ANA miles, I was able to get the below flights (including flight to / from china) in business class:

Shanghai(Pudong) ChinaAir CA 805 -> Bangkok

Bangkok Thai Air TG614->Beijing.

I am curious if anyone has any idea as to the quality of business class seats on these flights? I generally only fly ANA or JAL business on mostly transpacific (NY/Tokyo) flights and the seats are full flat and pretty comfortable. I checked the price for CA805 to Bangkok and was shocked to find the price for business class was under $500, and that got me very worried about the quality of business class and seats.

Any info appreciated.
