If you aren't earning Amtrak Guest Rewards points, the most common reason is that your member number wasn't added to the reservation at the time of booking. Unlike some programs, Amtrak typically requires the number to be attached before travel, though you can request "missing points" for up to 120 days after your trip. Other reasons include traveling on "non-point-earning" fares, such as certain deeply discounted tickets or tickets purchased using existing points (reward travel does not earn more points). Additionally, points do not post the moment you buy the ticket; they generally appear 7 to 21 days after the completion of your travel. If you are using an Amtrak credit card, ensure your card is properly linked to your Guest Rewards profile. Lastly, remember that points can only be earned by the person physically traveling; you cannot earn points for a ticket you purchased for a friend or family member in your own account.
