To each his own. I would fly UA 10 times out of 10 when compared to the SQ 359 -- it was by far the least comfortable lie-flat seat I've ever flown anywhere. I'd take angle-flat seats over it.

None of that is relevant, though -- fly whom you want. but unless you get very lucky, in that they decide to do another massive inventory dump and/or somebody in SQ IT makes a mistake -- don't expect to fly SQ long-haul J on a MileagePlus award ticket.
