The Discover Business Miles Card is a good choice for business owners looking to earn something back for all of their purchases.  With this card, you will start out with an introductory offer of 0 percent introductory APR on balance transfers for the first 12 months.  There is no annual fee to the card, which is an added incentive!  Plus, you can earn double the miles when you use your card at eligible travel and gas locations.  You will earn 1 mile per dollar spend on all other purchases.  There are no restrictions for using this card including the allowance to book your trip any time you want on any airline and with any seat.  These features make this one of the most affordable of credit cards with airline miles.

You will be able to earn Double Miles up to $5000 in gas and travel purchase.  You can begin redeeming your miles at 5000 miles.  Redeem them for gift cards from one of any of the Miles partners (there are 50 brand name options to choose from.) 

You can also use your card to manage your quarterly and annual statements, and use the account for Purchase Checks when you need to.  Plus, give employees cards that you control spending limits on and earn Miles with them.
