Yes, that's one of the worst things about this change: the loss of the best Premium Economy class (and for that matter, the best economy class in the BKK-USA market too.) The loss of 36" seat pitch and 2-4-2 seating in economy will be missed. I don't like the 3-3-3 seating in the 777's. Many people travel as couples, and it typically means that for seating one is in an aisle or window, and the other is in a center seat. The A330's and A340's are much more desirable in that respect with their 2-4-2 seating.
