Yes, joining Amtrak Guest Rewards, the official loyalty program for the National Railroad Passenger Corporation, is entirely free of charge. In 2026, the program remains one of the most accessible ways for travelers to earn value from their rail journeys. Upon signing up for free on the Amtrak website or mobile app, members earn points for every dollar spent on Amtrak travel. These points can be redeemed for future train tickets, seat upgrades, or even gift cards and hotel stays through partner networks. The program features different "Elite Tiers"—Select, Select Plus, and Select Executive—which are reached by earning TQPs (Tier Qualifying Points) through frequent travel. While the basic membership costs nothing, the higher tiers offer premium perks like lounge access, companion coupons, and point bonuses. For the occasional traveler or the daily commuter, the free membership provides a way to track travel history and eventually "bank" enough points for a complimentary trip, making it a high-value, zero-cost safety net for anyone who uses the U.S. rail system.
