Amtrak’s reward program works much like most other reward programs. You earn two points for every dollar you spend, with a 100 point minimum no matter what you paid. You earn 500 points for upgrading to business class and 750 points for upgrading to first class. You can then redeem these points for free Amtrak tickets, hotel stays, car rentals, and gift cards. If you ride Amtrak I would suggest signing up for this program. It’s free to join. You can signup at the Amtrak Guest Rewards website.
