>>1981239ORY looks like ass, is full of nafris and has a pretty shitty layout with a lot of choke points but it's comfy as fuck due to the "open" roof deck on the last floor of terminal 4 (formerly South).
Not sure if it's still a thing but 10 years ago I flew on the early Air Berlin TXL-ORY flights (which were dirt cheap) quite frequently and when arriving at Orly around 7 having barely slept, there was nothing comfier that making my way up there and having a coffee and a smoke while watching planes before going to baggage claim, which would typically start a few minutes later.
Also has a few completely desert corridors and balconies and a soulful little people mover.
