I have been flying a lot more aa recently because dl pricing has been so out of whack, I would say the d 1 lounge is marginally nicer than Chelsea but not enough to matter, I hate the 767 300, check in has been easy but I fly early or late, jfk just is an ever evolving mess but 8 tends not to be horrible
i would fly aa based on cheaper and my hate of the 767 300
