Ah, sorry maybe I was confusing.

Whether or not trips show up in the app, my goal was for my trips to be associated with my account (and show up in my account). I added my member number to every trip initially-booked without a member number, yet when I login to my account on desktop, nothing is there. This seems like a pretty standard expectation (certainly how many airline FF programs work), and I wasn't sure if this was expected Amtrak IT behavior or a glitch.
