The new Amtrak Visa is now up and running, offering 8000 bonus points with first purchase and no annual fee. Since it’s a Chase card, it may be churnable (Thus far, only the United card seems to disallow signing up over and over to pocket multiple bonuses).
Now, I still recommend the Starwood American Express as the best all-purpose credit card. And specific charges warrant some special-case cards.
But as far as truly no annual fee cards go, this one isn’t bad… although I don’t trust the underlying Amtrak Guest Rewards loyalty program, given its history of making changes without any notice whatsoever — miles used to be transferrable to outside programs without a cap and United used to be a transfer partner, for instance. Both changes were made without notice. And an increase in Amtrak train travel redemption levels was also dropped out of the sky without warning.
