What are Amtrak's rules for changing award tickets? I'm likely to want to make a few train trips next year, but I can't predict the dates. I'm wondering if it makes sense to do make some speculative bookings, not knowing when I'll really want to use the tickets. I typically travel in the northeast corridor, where the current 4k price is very tempting, but most trains on my routes are all-reserved. And I'm typically transferring points in from Chase UR, which is what I would have to do for these tickets.
