Yes, I am experiencing the same issue. I just got off the phone with the Diamond Desk. Just as you stated, all information is correct as they can see it, but if I look at it through delta.com, some itineraries are missing the info. I can correct it online and it will stay for some period of time. Then, I go back and check them, and Viola, it's missing again. This is extremely annoying. I'm afraid that my "A" fare trip to SAN on 11-1 will get cancelled and I'll lose my seat up front. The Diamond Desk assures me that everything is OK. I guess I'll find out for sure 72 hours prior to my trip
