Update: Some offers mentioned below are no longer available. View the current offers here.Update: The 30,000-point bonus is no longer available. The bonus is now 25,000 points for the Starwood Amex business and personal cards.As I wrote earlier today, the 50% Amex Transfer Bonus to Starwood points that was supposed to run until March 31, 2012, had been pulled early. A lot of TPG readers wrote in about it to let me know and ask if anything could be done about it.I emailed my contacts at American Express looking for some answers, and they responded immediately that they would look into it. It turns out the cancellation was a mistake, and the bonus has been reinstated. You can see it hard-coded into the transfer ratio on the Membership Rewards transfer page in the screenshot I just took below.As you can see in the calculator, the transfer ratio is back to 2:1 for the promo.Props to Amex for fixing it quickly–good things can happen if you speak up!This bonus is especially attractive if you wanted to take advantage of US Airways current limited time 50% bonus promo on hotel transfers. So 40,000 Amex would equal 20,000 Starwood which would transfer to 37,500 US Airways – a near 1:1 transfer to US Airways miles, which are generally better than the direct Star Alliance Amex transfer partners of Aeroplan, Singapore and ANA.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

I can often get over 4 cents per Starpoint in value when I redeem for Cash & Points stays, so if you value Starpoints at more than two times Amex points, this transfer bonus might make sense. Plus, Cash & Point and award stays now count towards SPG elite status and Starwood added a ton of benefits to Gold and Platinum status.
