Actually, there is a sort of an Amtrak FF plan, operated in conjunction with a Capital One Bank Visa Card. I don't know much else about it.

The former Custom and Club Class on Northeast Direct, Empire Service, and Keystone Service trains are now called Business Class. (These services will be called Acela Regional sometime next year.)

The former Club Class on Metroliner trains is now called First Class. Metroliner coach is now called Business Class. Next year, the Metroliner will be replaced by Acela Express.
