Apologies for this being in the slightly wrong forum, but I'm getting a very strange answer in the DL forum and from Delta (http://www.flyertalk.com/forum/showthread.php?t=752107)

Normally, whenever I book a KL/AF codeshare on nwa.com, I get a KL/AF PNR as well as a NW PNR. I recently booked an AF codeshare on delta.com, and I have a DL PNR but no AF PNR. I tried calling DL to get a PNR, they said it didn't exist, and the reply in the Delta forum has been the same. Does anyone know if Northwest does something different, in terms of being able to assign PNR for partner Skyteam airlines, or am I getting a weird story from Delta?
