1.Scheduled return Saturday 1:00PM SFO-SLC-DTW on DL. There were better options with availability, eg 12:30 non stop on NW, but neither NW nor DL would permit it. At 11:15AM received a call from DL but despite long wait on hold, no information. I called DL and after a few minutes was assured no problem. Again received a call from DL and now told the flight was delayed enough that connection was missed and we had been rerouted on the 9:45PM NW non-stop.By now (12 noon), of course, the 12:30 non-stop and other options were unavailable. Spent 10 hours in the SFO President Club. (BTW, the PC indicated that we may still have access until near end of year--nothing definite yet)

2. Tomorrow AM my wife (also Plat) is scheduled DTW-SLC. Traveling with pet in cabin.Not upgraded, but 6 of 12 first class seats remained as of early afternoon today. Tried unsuccessfully to checkin online (probably unable bc of pet), so unable to see her position on the upgrade list.Suddenly all FC seats gone, and Delta says "well of course, her SkyMiles number is not in" Right, only her WP number.

As of today we have almost never upgraded on DL flights.
