For my October - November Trip to Japan
Aug
15
On October 31, From Seattle -> Los Angeles -> Beijing -> Kansai
On November 13, From Haneda -> Beijing -> Los Angeles -> Seattle
It takes over 20 hours one way. But it is one of the cheapest business class I have ever flown being everyone by at least 1/3 or $1,200. It is still over 2 months away, but I will let you know if I want to do this again or not.
