I don't mind paying more if I could be guaranteed that the middle seat would stay open. I understand that it costs more for UA to keep customers and employees socially-distanced and safe, and those costs must be offset by charging higher fares. But I resent paying higher fares and UA does not make any reasonable effort to keep us safe.
UA has a right to try to sell and fill every seat. But they should be transparent about it, and the fares should be priced accordingly. I honestly wouldn't mind an "add-on" to a reasonably-priced fare to guarantee an open middle seat. (Sorry if this post is crossing over into "open middle seat thread" territory.)
