I have less money to spend on travel than I did a few years ago, but I think I'll be traveling on Amtrak more often. This is because of the extremely generous AGR program, and the AGR mastercard too. They seem to be popular with railfans, too - does anyone know what percentage of sleepers are taken up with AGR redemptions? I've always heard that most business & first class seats on airplanes are occupied by people frequent fliers - if Amtrak's AGR program is more popular than it was a few years ago, that may be the case for higher fares.
And I second the notion for choosing seats - most airline websites allow you to see the plane's layout and choose your own seat. If they could do that in coach, it might free up some time for the OBS crew - they wouldn't have to spend any time saving seats, reassigning seats, or any of that. And, in the sleepers, it would ensure that first-time travelers get a better look at their actual assigned room.
