After a schedule change, I changed my DL award ticket last night with the help of a good SLC agent. I now have 5 DL and 2 KL flights in my reservation. Flights show ok on DL.com and SaudiAirlines.com, but on AF.us and KLM.com only 2 flights show from this reservation: one DL and one KL flight. I can change seats just fine for the Dl flights on DL.com. Note that this reservation contains a problematic intra-Europe KL flight that was "selling out", but the agent was able to push it through somehow. Should I be concerned about what AF.us/KLM.com display? I tried looking up by both DL PNR and ticket number and the end result is the same.
