I've flown both Air France business class from JFK
on a 773 and I've flown tons of Delta 763ER business class flights from the U.S. to Europe.
There really arent that many glaring differences in the overall comfort of the biz seat. However, I will point out a few important differences: AF
seats in J have a massage function which is very nice. Also, the TV
screen on the AF
flights are much bigger then DL
's plus with AF
's are built into the seat back in front of you so there is no need to stow the personal monitor during landing. Again with AF
, the TV
doesnt interfere at all with meal service. With DL
, the TV
monitor kind of gets in the way of the tray, often the tray actually fits in snugly under the TV
monitor which I dont really care for.
With Delta, you get really great noise cancelling headphones. AF
gives you basic headphones, similar to what you might receive in coach. Delta gives you a very nice comforter and an oversize pillow. AF
I have slept comfortably in both of DL
's and AF
's biz seat. However, if I had the choice to fly from the U.S. to Europe via DL
business class I would choose AF
because of the smoothness of the T7.
As for the meal service in J, I would give the advantage to DL. It seems that the DL cabin crew work tirelessly and endlessly to please you and to make sure your happy. If your wine glass is empty they will fill up, remembering what you are drinking so you dont have to tell them. The food on DL was better then AF but not by much. I would say the overall attentiveness of the business cabin staff tilts in DL's favor.
Hope this helps. Also, I have recently compiled some trip reports on both the AF and DL business class cabins on flights I had done this year.
