The next set of 22 (551 to 572) have a ton less seats (again according to the wiki above) 148 (16,12,54,66). I may have expected 10 less but not 44 less seats. The final 321ceo interiors are set up for 192 (20,29,143). The remainder of the 155 321neos - are they going to be in the neighborhood of 190 seats?....which is probably a good replacement plane for the aging B757's (for the -200 series) as the -300 series has around 220 seats, and are younger than the -200 and will probably be around a few years longer. Their interiors and also the twin isle B767-300ER's have very close to the same number of seats. These 2 groups will be the holdout for the still unknown Boeing B797 twin (isle and engine) replacement. Did I see a thread where Delta was in talks with Boeing on B737 Max 10's..........why? what are these planes supposed to be replacing? and yet again another version for training, etc etc etc. Bad move. Either Delta should look at an A330-200 (or -800neo) as they would hold approximately the same number of seats as the B767-300ER's and the B757-300's. The only other plane that might work is the smallest B787 (-700 I think) which is more for international and long haul routes, so, not a good fit here either.
