I'm well within the three day window on this flight and it is showing: (thanks etour.jp!!)

NW 746 MSP 1657 DTW 1944 320 0
P3 F5 Y4 B3 M3 H1 Q1 V1 K0

Yet, no auto upgrade for a Gold. I called and they told me that there were only seats for sale. If true, shouldn't the above read F0?

BTW, this is for 5/29 flights
