The UA SFO-KIX is the only non-stop from NA. The F "suite" is a big seat. That's about it. Last time I flew the route the F cabin was full... of staff and a couple upgrades.

Service was awful, so was the food (that's out of KIX, it can only be worse for the reverse). KIX lounge was also very basic Japanese lounge.

On the other hand, ANA was so much better in every aspect. Even the lavatory is bigger so you have room to change into the complimentary PJs. Made-up bed, Krug champagne, caviar, gourmet dining (none of the above with UA food court dining ).

NH F cabin had only a couple other passengers, so I always had a separate bed made up.

Also flying out of NRT instead of KIX, you have real first class lounge.
