The fact that United flew these planes for years and there was ability to add 20+ seats to an aircraft and chose not to, to me seems inept. Those seats should have gone in sooner, once the technology and design was there. I understand passenger experience matters, but density and passenger experience aren’t mutually exclusive. United in this config preserved F and E+. What concerns me the most is I hope the company configed the aircraft right to not detrimentally harm flight attendants work space (this happened with Delta). The toilets are a concern but I think if placed in the right space (unlike DL 739s which send everyone to the back) less toilets if spaced appropriately can be ok.
