American Express runs a promotion once a year where they raise the sign-up bonus for the Starwood American Express Card to 30,000 from 25,000.
We like the card and posted a review of the Starwood American Express Card recently.
Starpoints can be transferred to a range of airlines.
Starwood also has some (not too many) good hotel redemptions in category 1-4 left. I rarely redeem for category 5-7 since I feel cash is a better use.
A $5,000 spend is required to get the bonus. If you read some of the posts about 'Manufactured Spend' at our site you should have no trouble achieving this quickly.
