Ok, I know Business on DL (BE) is an international product, as is the "D" fare class. However, DL.com read out an interesting fare and flight to me today.. it claims that IAD-ATL (Dec 22) on DL332 is a "D" class fare, and the seat maps show a business section... but this is a 737-800!??

Wasn't it the 800's that used to fly the DL shuttle routes? What were they configured as, and what does all this 737 "D" fare stuff mean. I'm confused.

Does this flight just have regular DL First class type seating? Or all coach? Or something in between??
