My first post in this thread.
Decent amount of dates available starting in October of 2014; though you do need some flexibility. Slightly less expensive if you add a connection in CDG (KLM/AF combination).
While perhaps, not the "best fare," it is a very decent fare (IMO) for the daily
KLM nonstop (with new Business Class configuration on a 747). Also earns requisite bonuses for KLM/AF/Delta mileage programs.
1.857,33€ all-in roundtrip (business class, Z fare).
The flights I just put on courtesy hold for 48 hours :
