Just driving up the QEII and all of a sudden I see a BA tail. Sudden confusion. I don't think BA's ever flown to YEG, and while they still (pre-pandemic) fly daily to YYC, I never thought I'd see the plane here. It's definitely parking because of the pandemic, but is it the YVR plane, the YYC plane, or from some other place? Obviously a single plane doesn't go to the same destination over and over...but which BA destination would it serve once it's back in service? Or is BA just parking it here as a one-off?

Took a long walk and managed to get within 500 metres of the plane without tripping any alarms. Sorry for the awful digital zoom, but if anyone could use a digital resource to hunt down what plane this is, it would really satisfy my curiosity and I'd really appreciate it.
