My complaint with the US3 is that they keep on lowering their product because, instead of saying "we are better than the LCCs", now they roll out this basic economy nonsense and non-elites have to pay for aisles or windows because they are "preferred" seats prior to OLCI.
So their reputation is harmed because those of us that avoid LCCs are now stuck with the same lousy seat pitch and nickel-and-dime purchase experience. And because they are the "big three", despite prices dropping customers expect more of them.
