I hate being cramped and crowded on a flight form the east coast to the west coast, I am small and many big americans seem to have no problem overflowing into my seating area. Next month I will be traveling from the east coast to Tokyo for the first time. premium is double economy and business class is double that . Is it worth it ? Looks like I'll be on JAL operated by AA, whatever that means. I've looked at seat maps but they all seem to point out that business class seats don't really lie flat, and that is an issue..?? Is nearly $6500 worth it? This is probably a once in a lifetime trip.
