Nope. I called the Plat line weeks ago about the seat, and after they changed it all flights still had KL flight numbers. Only after the "schedule change" two days ago did I end up with a DL flight number on the DL site, and an AF one on the KL site. All other legs still have the original KL flight numbers on both sites. The schedule as such did not change by even one minute.

In this particular instance the flight number change is immaterial from my perspective, so as the thread title says, it's just weird!
