I think you make some good points, but there should be a #0 that appears before all others: no one knows how this public health crisis, therefore this economic crisis will unfold.
This is the message underneath the town hall and the emails from RB. We could see anything from complete devastation to comtolete return of demand and the only way to know is wait, unfortunately...
I really doubt 50 seat flying will disappear from UA. Get cut, sure I mean everything will be trimmed. But disappear? Makes no sense to me. If pax comfort was such a big deal, they wouldn't pack economy seats into mainline planes. If they don't get scope relief, there is no way it will all disappear, but even if they do get relief, they'd need a heck of a lot of 175s flying to replace the seats in smaller markets.
Perhaps another good question is, if 50 seat flying gets cut by (let's say) 50%, whose flying is going away?
