I flew CLT-JFK-CLT this past week, East Crew and Metal from CLT-JFK, plane was nice, except the belts werent crossed and the seatback material was not in order, it was the plane's second leg of the day it RON in IAD and flew IAD to CLT.
The east crew seemed a bit overzealous on making sure everyone was obeying the regs, they were very strict and stern about it, not cordial.
Flew JFK-CLT on west metal and crew, same thing, plane came from PHX-JFK and made up my CLT flight. Seems US doesnt care about the appearance of an airplane on turn flights. Seat belts werent crossed and seatback material was all out of order. Plane arrived at 4:50pm for a 6:15pm departure. West Crew seemed nice, not as stern as the previous flight but still made sure the regulations were adhered too.
Overall it was a pleasant experience on both flights, except for the appearance of the cabin on turn flights.
