Not necessarily a bad change at all but given that the pmCO 777s from EWR and IAH go back to either destination I wonder how they'll manage the operations now. Does that mean another pmUA destination will go pmCO?
Someone alluded to the 737 debacle but this is nothing like that change. If you are in a premium class you still get the lie-flat business cabin. I'm just surprised there isn't more of a demand for the F cabin NRT-SIN.
