The only additional information that I got was that there will be a way to convert into the Starwood program, but the details weren't there yet. The reason that this is is so exciting, if 1 AmtrakReward Point equals 1 Starwood Point (to make it like the CO and UA transfers) that would be great because Starwood points can then be transfered 1 to 1 to many airline programs.

Even more interesting would be if they allow reverse transfers from CO or UA into Amtrak. Then, we could launder miles from CO or UA to Amtrak to Starwood to AA (or any other freq. flyer program).
