It’s all anecdotal but the Silver members of my household account are far more frequently upgraded than the Golds. That could be because of the routes and times they fly, or because they are more likely in WT+ whereas I would book myself CW when not having them in tow. However, of the 5-6 times I have flown WT+ as a Gold, I never got a thing. Neither an opup nor even a greeting. Master Tafflyer as Silver is curenly on 4 out of 6 sectors this year. These are all either LHR-MIA or LGW-MCO around college start and end dates.
