Delta launched SkyMiles in 1981, the same year the modern frequent flyer program was invented across the industry. American Airlines' AAdvantage and United's Mileage Plus debuted that year, and Delta's entry established the pattern: award free travel to repeat customers to lock in their loyalty, financed by the marginal empty seats on existing flights.
Through the 1980s and 1990s, SkyMiles grew into one of the largest programs in the industry as Delta expanded to national and international scale. The program added elite Medallion tiers, mileage-earning partnerships with hotels and car rental companies, and mileage expiration rules that Delta later removed entirely, an unusual consumer-friendly stance that became a marketing point.
The American Express relationship, dating to the 1990s, transformed the economics. Delta sells miles to American Express, which uses them to reward co-brand cardholders on spending rather than flying. The card portfolio expanded to consumer, small business, and premium Reserve cards. By the 2020s, the AmEx partnership was generating on the order of $7 billion annually for Delta, making SkyMiles effectively a payments business attached to an airline.
The program's most significant structural change came in 2015, when Delta switched from distance-based to revenue-based earning, awarding miles per dollar spent rather than miles flown. The shift, followed by competitors, reoriented loyalty value toward high-spend travelers and premium cabin buyers. Delta has continued refining Medallion qualification around spending thresholds, including a 2023 proposal that would have sharply raised elite requirements and was partially walked back after customer backlash.
As of 2025 and 2026, SkyMiles is among the largest loyalty programs in the world by membership, embedded in Delta's strategy of monetizing loyalty economics separately from ticket sales.

Free cash flow was a record $4.6 billion. For FY2026, Delta guided adjusted EPS to $6.50-$7.50, representing approximately 20 percent earnings growth.
Who founded Delta Air Lines?
Delta Air Lines traces its origins to Huff Daland Dusters, established in 1924. In 1928, Collett E. Woolman and investors purchased the company and renamed it Delta Air Service, after the Mississippi Delta region. Woolman led the airline for decades, building it into one of the major U.S. carriers.
What is the SkyTeam alliance?
SkyTeam is a global airline alliance of which Delta is a founding member. The alliance includes Air France-KLM, Korean Air, Aeromexico, and other international carriers, enabling Delta customers to earn and redeem SkyMiles on partner airlines and access partner airline lounges.
What happened with Delta and CrowdStrike in 2024?
In July 2024, a faulty software update from cybersecurity firm CrowdStrike caused a global IT outage that severely disrupted Delta's operations, resulting in approximately 7,000 canceled flights and an estimated $500 million in losses. Delta subsequently filed a lawsuit against CrowdStrike seeking damages.
SkyMiles' controversies center on devaluation and elite access. The 2023 announcement restructuring Medallion qualification around higher spending thresholds, including changes to Sky Club lounge access, produced an unusually intense customer backlash that forced Delta to revise the plan within weeks, adding rollover paths and softening thresholds.
Consumer advocates and DOT scrutiny of loyalty programs industry-wide have targeted dynamic award pricing and the difficulty of comparing award costs across programs. Delta removed published award charts, making redemption pricing opaque, a practice shared by competitors but criticized as reducing transparency.
Sky Club overcrowding as premium card portfolios expanded produced visible complaints and entry restrictions in 2024 and 2025, a consequence of the program's commercial success straining the lounge infrastructure behind it.
