50181 mi / 44 segs (about 55% on AC metal)
But I've got YVR-SFO-SYD-MEL booked, and there should be a YVR-HKG in my not-so-distant future, plus all of the usual work flights (mostly "transborder"). Should add up to somewhere around 125–150k, weather permitting.
As others have noted, since the T/T+ mess that is AC Canada–Asia flights now, I'm not sure whether I'll fly AC to HKG (though that's one of my favourite flights); certainly there are a lot of options if one wants to fly to, eg, LAX first.
