Yes, if you made your reservation online, visit Amtrak.com and select “Modify Trip”. Log into your Amtrak Guest Rewards account or enter your reservation number and email address to upgrade to Business Class. You can also call 800-USA-RAIL to upgrade. You’ll be charged the difference in the fare between Unreserved Coach and Business Class, which is $10 to $35, depending on the distance traveled. Seats are limited, and it is possible Business Class seats may sell out on certain trains, so we recommend doing this in advance of your trip.
