The link

says

"Turn your Starpoints into Amtrak Guest RewardsŪ points for free travel and other rewards. Starpoints convert 1 to 1 with Amtrak Guest Rewards points."

However if you click on the transportationlink just above it, it has no info on how to transfer starpoints to amtrak guest rewards program.

Any one have any info on this?
