They are going from 72 coach seats to 123. That’s significant IF they get the yields. Plenty of people still fly on price alone for coach, with schedule being of second priority..
The reduction in MCE seating is the most glaring issue IMHO. Especially when DL and UA are actively increasing their extra-legroom inventory. People will get used to the new J seats and stop complaining...
...the length is going to be an issue for anyone over 5’9” or 5’10”
I thought these were supposed to be 78 inch "beds"...so that must mean there's a 1-2 inch wide corner spot where a 6-footer can point their big toe (and speaks to the cramped perception being reported vs jetBlue). While I think this plane will serve transcon flights totally fine, I am skeptical all around that any of the cabins will be profitable on overseas flights. I am slightly more optimistic that UA can deploy them protitably, but I think they've also over-ordered the type.
