This is what I specifically asked about and quoted to them and they're assuring me that's not the case because I'm booked in G class which isn't in the program rules, and the new PS and Suites are causing them issues in the system for upgrade requests. So, anything I can do to prompt it? Now there are 8 seats, with 4 on the waitlist, all four for both PS and D1, and the flight from DC is around 9 am and from DTW around 12:30 PM. Perhaps I'll clear overnight? I've only ever used miles rather than a GUC on a KLM connection from Amsterdam, upgrading at the club, but I used my GUCs this year on an earlier vacation.
