I recently changed jobs and the company I went to work for issued me a Citibusiness Aadvantage Mastercard. I haven't figured out any way I can personally benefit from any miles or other perks. They require me to use this card for all my gas, hotels, food, etc. Basically ALL expenses. Any thought or ideas would be welcome. Keep in mind I have to provide receipts for each transaction and they match this up against the card billing. I'm afraid I'm out of luck on this..
