so i've had a credit card before, but it was a joint account with my father. It had my name on the card, but technically it was under his account. The thing is, I fly Northwest/Delta the most (almost every time I go home from yeshiva), but its only about 500 miles one way from detroit to New york, so I haven't racked up that many miles. I just flew RT to Israel on continental and took advantage of their double miles promotion that was posted on dansdeals.com a while ago, so I'm at around 23,000 which is more than I have over at NW/Delta.
