how to book a rewards ticket
 

Okay, this is going to seem like a silly question. How do I book a rewards ticket? I haven't done this in a couple years, and it looks like the webpage has changed.

I went to the AGR website for point redemption (https://www.amtrakguestrewards.com/redeem), and it just points me to the standard amtrak.com booking page, which is the page for cash purchases. I went through it a few times to make sure I wasn't missing anything, but there's no options or buttons for point redemption, it just keeps making me do cash purchases. What obvious page/button am I missing?

Start a standard purchase, and when you get to the search results, there will be buttons at the top to toggle between dollars and points.

Be sure your AGR account and Amtrak.com account are linked, and you are logged in to both. Then, as mentioned above, just search as normal, and at the top of the results, there is a radio button to select money, or points.

Hah okay, I knew it must have been one of those "duh" moments. Missed the button up top (admittedly after a few drinks in). Thanks!

That hasn't been necessary for some time. As it now says on the Amtrak website,

I imagine a login is necessary to book the ticket, but I see the buttons for cash and points even regardless of my login status.

Ditto here. No secret trick to see the buttons.
