I am pretty flexible in my travel from SEA-HKG. I can route via YVR, SFO, or LAX. This gives me a few options on aircraft to take as well.

Any opinions on the best aircraft?
340-300 (34C or 34D) or 747-400 (744 or 74J)

I'll most likely be in Economy, however, there is always hope of an upgrade!

Which one is most likely to have AVOD/ new interiors? Which would you suggest?

Are they flying the new 747 product to the US yet?

Thanks so much!
