I was on a flight recently, purchased with award miles and received a CPU 4 days before the flight. I am a 1K and it was my understanding that award flights are not CPU eligible. My wife, on the same flight, but a different PNR, with the kids, did not receive an upgrade. Her ticket was also on miles and she is also a 1K through MM.

Just wondering what happened? And before anyone asks, I had to give my first class seat to my wife
