This week: Delta's SkyMiles program was just valued at $31.78 billion. It’s a record, and the fourth year running it's held the top spot. AAdvantage came in at $26.7 billion. MileagePlus at $25.3 billion. The On Point Loyalty 2026 report puts the combined value of the top three US programs at over $83 billion.

For context: Delta's market cap at several points over the last three years has been lower than the valuation of its own loyalty program. The plane-flying business is worth less than the points-selling business.

Once you see that, the devaluation wave stops looking like bad customer service and starts looking like what it actually is: shareholder-driven margin expansion on a high-value financial asset.

The most valuable airline loyalty program in the world, for the fourth year running (On Point Loyalty Top 100, March 2026).

68% of that value comes from credit card revenue. 22% comes from the Medallion elite program. The planes are a footnote.

In 2024, Delta booked $7.4 billion from its Amex partnership alone. The 2029 target is $10 billion annually. Every time someone swipes a Delta Amex at a grocery store, Amex pays Delta. That revenue doesn't care whether planes fly.

On March 31, On Point Loyalty published its annual ranking of the world's most valuable airline loyalty programs. Delta's SkyMiles topped it at $31.78 billion — a record, and the fourth year running it's held the spot. AAdvantage came in at $26.7 billion. MileagePlus at $25.3 billion. The top three US programs alone are worth over $83 billion.

For context: Delta's entire market cap has been lower than its loyalty program valuation at several points over the last three years. The plane-flying business is worth less than the points-selling business.

Once you see that, the wave of devaluations that hit between December and now stops looking like bad customer service and starts looking like what it actually is: shareholder-driven margin expansion on a high-value financial asset.

Since December, the cuts have come in a cluster. American ended AAdvantage mile earning on basic economy from December 17. United stripped mile earning for non-cardholder basic economy from April, killed the Excursionist Perk, and pushed upgrade awards onto dynamic pricing. British Airways Avios went through a broad devaluation in December. Lufthansa Miles & More moved Group-operated awards off a fixed chart last June. Capital One cut its Emirates transfer ratio from 1:1 to 1,000:750 on January 13.

The pattern is obvious. What's less obvious is why it accelerated now.

🔴 HIGH
Delta-Amex is the template. 68% of SkyMiles' $31.78B valuation comes from credit card revenue. The rest of the industry knows it. Expect every major carrier to push co-brand expansion hard through 2026, including the European carriers that have historically been behind on this.

🔴 HIGH
Basic economy is the wedge. American and United both stripped mile earning from basic economy within four months of each other. This isn't a coincidence. It's the industry finding a way to devalue without touching headline program mechanics. Expect Delta to follow within 12 months.

🟡 WATCH
Dynamic pricing is now the default. SAS is actively hiring a Product Owner for Dynamic Pricing. This is a program that ran on a predictable chart until very recently. When SAS goes dynamic, the transition is effectively complete across major Western carriers.

🟡 WATCH
Transfer ratios are the new devaluation lever. The Capital One-Emirates cut to 1,000:750 is a preview. When programs can't visibly devalue their own charts without reader revolt, the transfer partners quietly do it for them.

🟢 CONTEXT
Southwest is the outlier. For now. New leadership, a stated commitment to strengthening the program, and a relative under-performer in the rankings. Worth watching whether this becomes a real counter-trend or just a press release.

The clearest breakdown of the $31.78B valuation math. 68% from credit cards, 22% from elite program economics. The mix tells you where airlines will invest next.

A consumer view of the same story. The "access walls" framing is the right mental model for what airlines are actually doing.

View from the Wing: American's 2026 AAdvantage leaked changes
The leaked elite benefits page and the reader comments are a good proxy for how the top 1% of flyers are feeling. "I couldn't give a damn about status and loyalty anymore" is a sentence AAdvantage management should read twice.

A warm welcome to the new subscribers who joined this week. Glad you're here.

A small admission for this one: I came into the research expecting a customer-side story about devaluation frustration. I ended up writing a financial-engineering story. Loyalty programs in 2026 are not really about flying anymore. They're about managing a balance sheet asset. The customer experience is a side effect of the cap table.

That framing makes a lot of industry behavior legible in a way the "airlines are greedy" narrative never quite did.

Hit reply and tell me: are you still chasing status on a major program, or have you given up and gone back to cash? I want to know what the shift looks like from the member side, not the airline side.

P.S. If you work in loyalty, revenue management, or airline distribution, I'd love to hear your read on this. Forward this to someone who lives inside these programs. Their reaction is probably more interesting than anything I wrote.

Thanks for being here.

See you next week!
