Typically it is run 6 days a week (not on Saturday I think). Flown it twice round trip (twice in Y, once upgraded in J and once rewards J), nice flight to get to LHR without having to go through YYZ, and shorter too boot.

I don't have any security/check in issues, and it's my home airport. I don't usually check much in the way of bags and I use the standard ziplock bags you get there (replacing it when it falls apart). Could be the difference.
