The bean counters running the Amtrak loyalty program never cease to amaze me.
A couple years ago they had a great transfer offer with United that allowed you to transfer United miles into any other airline miles.

Today, without any prior warning, Amtrak took away the ability to transfer to Choice. It merely says that it is “temporarily unavailable.” The exchange rate is no longer even listed. Given the underhanded way in which the Amtrak program is run, it wouldn’t surprise me if it will never even make a return at all…
