there was a guy 2 years ago who _lived_ on air canada planesl for 2 solid months because at the time Air Canada was dumb enough to give out STATUS miles for flying on their passes.
it was a $7,000 pass good for unlimited travel within Canada for 2 months.
he would do stuff like fly short haul an hour or two during the day then take a long haul cross canada flight to sleep. and shower in the maple leaf lounges.
he ended up with just over 1 million aeroplan miles.
