I connect YQU-YYC/YEG-> and YXS-YVR->

to YYZ, YUL and IAH being most of my samples: As an E last year it seems I was getting my upgrade while E's and SE's where told no. As an SE this year I've gotten my upgrade while other SE's who are directs did not. I have never not gotten a upgrade on YYC-IAH when connecting from YQU, where if I'm direct from YYC it seems 50/50.

I fly paid J to asia so I haven't been able to test this on a long haul yet, but I do have a trip to LHR coming up and will see how it works out.
