Most? I guess you all are a good deal wealthier than I am. Flying in J is nice and all, but the extra $2K or so isn't just pocket change to me. I consider that to be serious dough and I can think of a lot of other ways that I could better spend that kind of money.
Agreed. One simply needs to look at the seat map and see that "most" are looking for Y, presumably cheapest available. (And no way I'm flying via China, not even in J.)
