If you have the personal Visa or Amex I talked about here, you’ve already picked up at least 75,000 American Airlines miles. Here’s a quick way to grab a few more:
Call the number on the back of the credit card. Tell them you want to cancel because of annual fees or better miles on another card. They will immediately transfer you to the retention department and offer you a deal. My deal was an $85 statement credit and 750 extra miles per month (for 12 months). Give it a shot and see what you can get!
