Delta also has partnerships with both hotel and car rental companies where you can transfer points into Delta SkyMiles at varying transfer rates. Some partners include ALL-Accor Live Limitless, Radisson Rewards, Marriott Bonvoy, Hilton Honors, IHG One Rewards and Hertz Gold Plus Rewards.

Yes, Delta SkyMiles has an extensive network of transfer partners in 2026, though it functions more as a "receiver" than a "sender" of points. You cannot transfer SkyMiles out to other airlines or hotels; once your miles are in the Delta system, they must be used for Delta flights or SkyTeam partners. However, you can transfer points into Delta SkyMiles from several major rewards programs. The most prominent partner is American Express Membership Rewards, which transfers at a 1:1 ratio (though a small excise tax offset fee applies in the U.S.). You can also transfer points from major hotel loyalty programs like Marriott Bonvoy (3:1 ratio), Hilton Honors, and IHG One Rewards, though these generally offer poor value compared to using the points for hotel stays. In 2026, Delta also maintains "earning" partnerships where you can accrue miles through everyday activities like riding with Lyft, booking with Airbnb, or shopping through the SkyMiles Shopping portal. This one-way "inbound" transfer system makes Delta miles very easy to accumulate for frequent flyers and credit card users looking to book award travel across the globe.
