You can transfer Marriott Bonvoy points to Southwest Rapid Rewards at a rate of 3 Marriott points to 1 Southwest point.
For example, 10,000 Marriott points convert to 3,333 Southwest Rapid Rewards points.
But you can score an even better deal by transferring in increments of 60,000 points, which gets you a 5,000 airline points bonus, which lowers the transfer rate to 2.4 Marriott points to 1 Southwest point.
For example, 60,000 Marriott Bonvoy points convert to 25,000 Southwest Rapid Rewards points.
Typically, transfers from Marriott to Southwest take about 24 hours to complete, so be aware of this delay when booking travel.
How to Transfer Marriott Points
To transfer points from Marriott Bonvoy, follow these steps: I recommend transferring in increments of 60,000 Marriott points because there is a 5,000 airline mile bonus when you transfer 60,000 Marriott points. This 5,000 miles bonus does not apply to American Airlines AAdvantage, Avianca LifeMiles, Delta SkyMiles and Korean Air SKYPASS.
