If the mid2020s airline market is going to have a heavy dependency on freight, could we see a move back towards a 767-200/A310-300 size aircraft with 2-2-2/2-3-2 passenger layouts, especially if post COVID that there is a customer perception that narrower aircraft are more "confined"?
When the 757s got popular again post winglets, I always wondered what the numbers on an updated A310 would look like, but A330 deck and fuselage and something like Trent 500s under a tweaked A310 wing.
