As of February 13, 2019, the Marriott Rewards, Starwood Preferred Guest®, and Ritz Carlton Rewards have all been combined to form the Marriott Bonvoy™ program.
Starwood Preferred Guest® is one of the most beloved hotel loyalty programs. One of its strong features is the program’s incredible versatility, as you can transfer Starwood Preferred Guest® points to dozens of airline mile programs at a 1:1 ratio, rare for a hotel program.
Even more so, when you transfer 20,000 points, you get a 5,000 mile bonus, and you can get this bonus for every 20,000 points you transfer – it’s not limited to the first 20,000 points you transfer.
The downside is SPG® transfers aren’t instant, so you’ll want to be very sure you can make use of the mileage program before you transfer. Some programs like American AAdvantage® and Korean Skypass will let you put awards on hold, but some of the most lucrative transfer partners like Alaska Mileage Plan and ANA Mileage Club won’t hold awards while you wait for the transfer to complete.
And while Marriott plans to acquire Starwood, it will be a while before this feature changes if that happens.

How to Transfer SPG Points to Airline Mile Programs
You can follow this link and enter your SPG username and password to go directly to the airline mile transfer page.
If you’re navigating the site, you can find it via the following steps:
1. After you log on to your SPG account click “Redeem Starpoints®.”
2. Click “Travel”, under the suitcase icon.
3. Scroll half-page down until you see “Transfer Air Miles” and click on it.
4. Click “Transfer Starpoints to Air Miles.”
5. Select your airline, enter the FF# and the amount of points you want to transfer, tick the T&C box and click “Go.”
Pay attention to the following SPG rule, as it might be confusing.
Starwood Preferred Guests can transfer up to 79,999 of their Starpoints® per transaction per program within a 24-hour period to the frequent flyer programs listed below. Plus, for every 20,000 Starpoints transferred within the same transaction, Starwood will automatically add another 5,000 Starpoints! This means that up to 94,999 Starpoints can be transferred into your frequent flyer account.
What it really means is there’s a 24 hour limit of 79,999 points transferred to any given program.
But you shouldn’t be transferring exactly 79,999 points in one transaction or you will miss out on the 5,000 mile bonus at the 80,000 point level (since 80,000 is a multiple of 20,000 points). It’s always best to transfer Starpoints in 20,000 point chunks, so the maximum you should transfer any given day is 60,000 points, which will get you 75,000 points (3x 5,000 point bonuses).
And beware, transfers are not reversible. Once you transfer out, you can’t transfer back into SPG.
- Alaska Mileage Plan has better prices for American Airlines flights than American’s own AAdvantage miles, as well as excellent rates on Cathay Pacific. It also has fantastic routing rules allowing you a free stopover on a one-way flight.
- Cathay Pacific Asia Miles gives you prime access to its own premium class award space and great Premium Economy rates from the West Coast (72,000 miles between LAX and HKG per roundtrip). It also has good stopover opportunities, and lets you book any OneWorld carrier, including American Airlines and Japan Airlines.
- ANA Mileage Club is one of the best programs, especially for business class flights to Asia (from 75,000 miles per roundtrip between the U.S. and Japan in Business!). ANA is a Star Alliance member, so you can book United, Lufthansa, and more.
- British Airways Avios has great levels for short hops in Europe and on partners all over the world, including American Airlines and Cathay Pacific.
- Etihad Guest offers pre-devaluation award charts for American and some weird and unexpected bargains for other partner airlines like Brussels Airways. A roundtrip flight between JFK and Brussels costs less than 22,000 miles in Economy and less than 36,000 miles in Business (with no fuel charges), though getting agents to book awards can be a challenge.
- Flying Blue has excellent levels for flights between the U.S. and Israel in Economy — only 50,000 miles per roundtrip.
- JAL Mileage Bank is the only program you can reasonably use to book a flight on Emirates without huge fuel surcharges (only 85,000 miles in Business and 135,000 in first between the U.S. and U.A.E per roundtrip). It currently doesn’t add fuel surcharges, although it did in the past.
- Lufthansa Miles and More has excellent levels for United flights in the U.S. in business class — only 35,000 miles per roundtrip. However, it usually adds huge fuel surcharges on its own metal and other partners.
- Singapore KrisFlyer is the only place to park your points if you want its celebrated First or Business Class award seats, as Singapore doesn’t share its premium class award space with partners.
Some SPG partners are better to avoid. Transferring valuable SPG points to United and Gol at 2:1 ratio is not a good idea, and there is little in these programs that can justify this ratio.
Instead you can transfer to Air Canada or other Star Alliance partners like Singapore or Lufthansa to book United in the Americas, or to Delta to book Gol.
You might also avoid transferring points to airlines that add huge fuel surcharges if you intend to redeem miles on their own flights, like Emirates, Virgin Atlantic, and a few others, as well.
