So, Delta's been expanding their A321neo operations lately. Just saw that they're planning to use these on more routes out of Atlanta and Boston. Honestly, I'm pretty excited because these birds are super efficient and have that newer cabin vibe. But I'm curious - is it the right move to put them on routes that have typically been served by older planes? I think it might be a smart play for fuel efficiency and passenger comfort, but I don't know how it'll affect their maintenance operations or if it fits all their routes perfectly. Anyone got thoughts on how the A321neo stacks up against their older fleets? Or any insider info on how this might change the in-flight experience?
