Hyatt and Delta announced a long-term loyalty collaboration on September 9, 2026, with a Dual Earn benefit for elite members of both programs and no published rates yet. The same day, Hyatt confirmed its enhanced relationship with American Airlines is ending, and preserving the wind-down benefits requires linking both accounts by 11:59:59 p.m. CT on November 15. What is ending, what survives, and why a Delta partnership is not a Delta transfer deal.
Hyatt published two press releases on September 9, 2026. The first one is the exciting one. The second one is the one with a deadline on it.
Quoting Hyatt's release directly:
"Hyatt Hotels Corporation (NYSE: H) and Delta Air Lines (NYSE: DAL) today announce a new, long-term strategic loyalty collaboration"
The benefit at launch is called Dual Earn, and both companies describe it the same way. From Delta's version:
"Delta Medallions earn miles for spend on qualifying Hyatt stays (in addition to earning certain other World of Hyatt benefits) and World of Hyatt elites earn points on qualifying fare classes in addition to earning certain other SkyMiles benefits."
Three limits are stated in the releases themselves and are worth reading before anyone gets excited:
It has not launched. Hyatt says the collaboration is "launching in the coming months." Nothing is live today.
It is for elites. Hyatt's own summary line is that "Initial benefits will focus on Elite Members." If you hold no status in either program, nothing announced so far applies to you.
The numbers do not exist yet. Hyatt says "additional eligibility and benefit details to be shared soon" and Delta says details on "enrollment, eligibility, earning opportunities" come "in the months ahead." How many miles per dollar, which fare classes qualify, which properties participate: none of that is published. Anyone telling you what Dual Earn is worth today is guessing.
So the Delta story is real, and it is also, for now, an announcement rather than a benefit.
We are tracking both programs for the actual terms, and we will publish the earn rates, the qualifying fare classes and the participating properties here as soon as Delta and Hyatt put them out. When the numbers land, this page gets them.
Hyatt posted a second item the same day, titled "Update on American Airlines and Hyatt Relationship":
"After careful consideration, we have mutually decided to not continue our enhanced relationship."
That one has dates, and one of them is a deadline you can miss.
"AAdvantage® members who have linked their AAdvantage® and World of Hyatt accounts by 11:59:59 p.m. CT on Nov. 15 can continue earning World of Hyatt awards through Loyalty Point Rewards through Feb. 28, 2027. World of Hyatt members who have linked their accounts by Nov. 15 can continue earning AAdvantage® awards through Milestone Rewards through Dec. 31, 2026."
Read that carefully, because the structure of it is unusual. The relationship is ending, but the wind-down is not automatic. It is conditional on having linked your two accounts before a specific minute on a specific night. Link in time and you keep earning through the end of the current earning year on both sides. Miss it and the transition provisions do not appear to reach you.
Linking is free, it takes a couple of minutes, and there is no version of this where doing it costs you something. If you hold both an AAdvantage account and a World of Hyatt account, that is the single action worth taking this week. November 15 is a Saturday, and the cutoff is 11:59:59 p.m. Central, not local.
The phrase in the release is "enhanced relationship," and the distinction matters more than the headline does.
Ending: the linked-account rewards. AAdvantage Loyalty Point Rewards that pay out in World of Hyatt awards, and World of Hyatt Milestone Rewards that pay out in AAdvantage awards.
Not ending, in Hyatt's own words:
"AAdvantage® members can continue choosing to earn 500 AAdvantage® miles in lieu of World of Hyatt points on eligible Hyatt stays by providing their AAdvantage® number at check-in even after the broader relationship concludes."
That option survives the breakup. If you have been giving your AAdvantage number at check-in on cheap Hyatt stays, you can keep doing it.
Whether you should is a separate question, and it is arithmetic rather than opinion. 500 AAdvantage miles at our published valuation of 1.5 cents is about $7.50. Whether that beats the World of Hyatt points you are giving up depends entirely on the rate you are paying, and on a base-tier stay it usually does not take much of a room rate before the points win. Run it per stay rather than setting it once and forgetting.
A Delta partnership is not a Delta transfer deal, and the two are going to get conflated all week.
World of Hyatt points already move to airline programs, including both of the airlines in this story, and this news changes none of those ratios. From our transfer partner records as of September 9, 2026, both American AAdvantage and Delta SkyMiles sit at 5:2, meaning 5,000 World of Hyatt points become 2,000 miles.
| Give up | Receive | Our valuation | |
|---|---|---|---|
| Hyatt to Delta SkyMiles | 5,000 Hyatt points | 2,000 SkyMiles | about $75 becomes about $24 |
| Hyatt to American AAdvantage | 5,000 Hyatt points | 2,000 AAdvantage miles | about $75 becomes about $30 |
Those figures use our own published valuations of 1.5 cents for World of Hyatt, 1.2 cents for Delta SkyMiles and 1.5 cents for AAdvantage. They are estimates rather than prices anyone guarantees, but the shape does not depend on the precision. Converting World of Hyatt points into airline miles destroys roughly two thirds of their value, it did so yesterday, and it still does today.
Dual Earn, if it lands as described, is the opposite of that. It is earning two currencies for one purchase rather than converting one into the other at a bad rate. That is genuinely worth having. It is also not here yet.
We will update this page the day Delta and Hyatt publish the terms, with the earn rates, the qualifying fare classes and the property list. Until then, nobody has those numbers, including us, and we would rather say so than fill the gap with a guess.
