Way back in 1976 or 1977 there was an Air Canada Aeroplan promotion. I was barely a teenager, and had to fly YYZ-YUL to pick up a Christmas present in Montreal and bring it back to Toronto.

The mileage was something like 350 for that route but AC gave 20,000! And my airfare was paid for by a relativeto boot. If they paid $200, and it might have been $136 it works out to 0.005 cents.

My first mileage run, and I didn't know it.
