It makes sense to double check short-haul segments on international itineraries with AF. Recently I saved a couple thousand dollars on the return portion of a CDG-IAD flight because the non-stop did not have discounted business class available. Thus, I asked my travel agent to book CDG-JFK-DCA which had Z class available on the transatlantic portion. Now when I look on the itinerary it states that the DL-partner operated CRJ flight JFK-DCA lists "La Premiere" as the cabin service because the flight segment booked into Delta P Class. Obviously, I never believed for a minute that AF would provide me their "La Premier" service on the short haul DL flight or any JFK transfer assistance that they may offer "La Premier" passengers.
