My WT+ opup rate has been 100% this year. Although since I have only booked one sector in WT+ this year I think the sample size may be a bit small to draw any conclusions. It was a LHR-YYZ sector out of interest and I was silver at the time.
What routes are you being lucky on Alwaysfly? I assume WT+ is very popular on some routes which tends to lead to all the opups.
