UA 842 was a 3 cabin premium 767 this morning from ORD to LAX. I thought it was just an equipment change but I just booked the same flight for two weeks out, then priced out a biz class ticket, and the seat map showed seats facing forward and backward. Maybe this is an intentional switch?? It would be nice, but it may not matter to me as I'm P1 and don't know that my 500-milers will ever clear.
