Booked another flight on United four our anniversary trip despite swearing never to do so again. We booked precisely because there were good seats available in economy away from the bathrooms and that recline. Reviewed our trip today to find they cancelled our seats and put us in the back of the plane by the bathrooms with no recline for 5+ hour flight. Called to find out what happened. Said they changed the plane to make sure it was packed full like sardines and just reassigned seats willy nilly. Adamantly refused to change our seats back to where we had originally booked and refused to refund the ticket. Don't seem to care about customers at all. Must be too busy stealing sand from public beaches for their mansions to notice how bad they are compared to other airlines.
