As I first wrote about in early August, Starwood Preferred Guest is offering a 20% bonus on points transfers to American AAdvantage.

Starpoints ordinarily convert into American AAdvantage miles at a 1:1 ratio, with a 5,000 point bonus for every 20,000 points transferred. This means if transferring in the right increments you can ordinarily earn 1.25 American miles per Starpoint.


Through this promotion 20,000 Starpoints would convert into 30,000 AAdvantage miles, for a total bonus of 50% — you get a 5,000 mile bonus as you usually would, plus an additional 5,000 miles through this promotion.

Anyway, it’s worth noting that this promotion ends today. 11:59PM CT tonight (September 14) is the deadline for transferring points under this promotion.

Generally I wouldn’t proactively transfer points from Starwood to American, though with a specific use in mind it could make a lot of sense. While many of American’s first class redemptions were greatly devalued earlier this year, there are still some good values for business class redemptions that are worth considering.

If you are considering transferring points, do keep in mind that you can only make one transfer every 24 hours, up to 79,999 SPG points at a time. The latter is a particularly irritating restriction, given the 20% transfer bonus when converting blocks of 20,000 Starpoints, so it rarely makes sense to transfer more than 60,000 points at a time.

Generally the best way to earn American miles through credit card spend is with the Starwood Preferred Guest® Credit Card from American Express and Starwood Preferred Guest® Business Credit Card from American Express. When transferring in the right increments you earn 1.25 American miles per dollar spent, and it can even better than that with transfer bonuses, like the one expiring today. If you’re an American flyer, it could very well make sense to use a card like that for everyday spend.

Bottom line

While I don’t think everyone should rush to convert Starpoints into American miles, this could represent an excellent value. American AAdvantage miles are one of the most popular mileage currencies out there, so being able to convert Starpoints into them at a 1:1.5 ratio is pretty great. You just have hours remaining to take advantage of this offer.

Will you (or have you) taken advantage of the 20% transfer bonus from Starwood to American?

  1. I want to do this (I need 3k miles for an AA award) but see no mention of it anywhere on the SPG site – just on the AA page screenshotted above.

  2. I have been on the fence about this one. That’s a great bonus – but something tells me I’d be happier converting my Starpoints to Alaska Air. When looking at J and F space, AS prices beat the others hands down in most occasions, plus the free stopovers on one ways.

  3. Would you suggest transferring them if you plan on booking a Cathay Pacific Biz award? Didn’t you have an article recently stating that Cathay was blocking award space?

  4. Just took advantage of this a couple of weeks ago. JAL biz is insanely valuable if you live in Boston since their nonstop to NRT is in the 787-900 with the Sky Suites now. We don’t get many 12+ hour flights here, and with Cathay, Qatar, and JAL, AAdvantage treats us well!

  5. I did this four or five days ago. So far, no changes to my account balance with American. I guess I’ll have to wait the full seven days.

  6. I did this for this promotion and the points, and AA bonus, posted within 48 hours. The transfer was completed on Sept 11.
