I tip my hat to you B Watson for your innumerable RTW's!
My sister's close friend does the small commute YYZ-YUL several times weekly. His reward was Elite status on AC. But... he owns the company, and has cash to spend.
When he constructed his new house in YYZ, a couple of years back he paid the contractor on Aerogold Visa. The bill was $13M CDN! That gave hime him 13 milion miles in his AC account.
Now comes the rub. Because he owned the firm, he wanted to protect his home. Therefore he put it in his wife's name. But his fatal flaw was using her Aerogold card rather than his. You see, she was basic, and he had just made SE or * Gold if you prefer.
13 million miles and no status!
