You get 1 Amtrak point/mile for every dollar charged on the MBNA Amtrak Mastercard. So, $5000 charged on the card gets you 5000 Amtrak points which gets you 5000 UA miles. It's a great alternative to the FirstUSA Mileage Plus Visa card. Same conversion rate, no annual fee, and you are dealing with MBNA instead of FirstUSA.
