Delta Business Class is dated in general, I agree though that the 767-400 is awful in terms of comfort. DELTA really needs to step up their soft and hard products in order to stay premium or offer an International F class products on some routes to stay competitive. I think part of the issue is Delta faces minimal competition on many routes so they can pass this seat on the 767-400 as premium when it is dated in comfort and look. Hopefully Delta improves their products soon!
