I'll set aside the very sad and disturbing news out of China for the moment.
But I hope this DL news about the MAX doesn't prove out. I am among the many who find the 739 as Delta's least appealing mid-size. Given the narrower fuselage (and yes, I do notice the hip and shoulder room differences) DL's decisions about cabin layout - which I'm sure were impacted by where the wing exits are and how to maximize density - makes it plain they skimped on the C+ section.
Maybe the 10's geometry will work out better, but I'd rather not find out. I am curious how the 321neo is going to be arranged. The 321s now in service are mostly great, but the C+ rows just forward of the exit doors are definitely sub-par (the two seat pair is a nice option). Having a clear section back to the overwing exits should allow a better LOPA.
