I'm hoping there are some experienced Chicago to Japan fliers that can help me out. I will be traveling to Japan several times next year - first time there, but quite experienced with other Asian destinations. I'd like to compare carriers - I had good luck as a Cathay Pacific high status FF and thought perhaps I can duplicate the experience with the Japan journeys.

My options - United (FF, not currently high status), JAL, or ANA. I would be booking Premium Economy. Cathay upgraded me about 60% of the time to business - I wonder if any of the carriers to Tokyo are quick on the upgrades?

Anyone who can compare the Premium Economy seats on the three above? Premium Economy in a separate cabin - or just front of the Economy?

Narita or Haneda - is one or the other better as a rule? I doubt that I will be continuing onto a domestic flight once in Japan, more likely going directly into Tokyo.

Any other comments on the ride with the three carrier possibilities would be most welcome.

Thanks!
