YYJ/YVR have a flight time around 15 minutes, and 500 status miles for *A. This works out to 30+ miles/minute, and you can do many legs in one day if you so desired. If you dig around, there was a guy last year who bought an unlimited flight pass, and flew back and forth YYJ/YVR/YCD all day long in his quest for a Million miles... then he did redeyes at night longhaul...
