How Much Are Delta SkyMiles Worth Compared To American AAdvantage Miles In 2026?

It can be difficult for airlines to truly distinguish themselves because all carriers fundamentally sell the same product: flights. Therefore, airlines need to find ways to differentiate the experience of flying from point A to point B, and that's where loyalty programs come in. By rewarding high-value customers with perks and benefits, airlines can essentially keep customers tied to their network and larger frequent flyer ecosystem. This is an incredibly lucrative side of the business. Within the US, American Airlines' AAdvantage program was previously the US's largest airline loyalty program, but it has been overtaken by Delta Air Lines' SkyMiles. The two programs, while being similar in many ways, also have a variety of differences. These may make one or the other more appealing to a specific customer. What's more, the individual value of a mile issued by these two programs is not necessarily the same. It's therefore important to know what the value proposition for each program is and which one is best suited for you. The Value Of An Individual Mile Credit: Robin Guess | Shutterstock The true value of airline miles is not a set figure, because this can change based on individual redemptions. However, it is possible to estimate mile valuations at a specific point in time based on systemwide redemption prices. NerdWallet estimates the value of one AAdvantage mile at 1.7 cents, while estimating that one SkyMile is worth 1.2 cents. Meanwhile, The Points Guy estimates that one AAdvantage mile is worth 1.45 cents, while pegging the value of one SkyMile at 1.2 cents. Across the board, AAdvantage miles are considered to be more valuable than SkyMiles, and this is a unique advantage for American. NerdWallet pegs a United Airlines MileagePlus mile at 1.2 cents, while The Points Guy values MileagePlus miles the same. There has been criticism of Delta and United for the devaluation of their programs' miles, and AAdvantage offers a material advantage in terms of redemption values. This is important when trying to decide which airline to be loyal to. At all three airlines, you can earn miles by flying or through credit card spending, which has become the primary means of mileage earnings in the US. The airlines offer a wide range of credit cards, each coming with progressively higher annual fees and increasingly lucrative benefits. In addition, all three carriers are part of airline alliances, which grant certain benefits when traveling with select airlines worldwide, and they also have individual partnerships with airlines outside of the alliances. Reaching Elite Status Credit: Wangkun Jia | Shutterstock Delta Air Lines uses four main Medallion tiers, as well as the general membership status and the invite-only Delta 360 tier at the very top. The four Medallion tiers, named Silver, Gold, Platinum, and Diamond, offer increasing rewards with each higher tier. In order, they respectively require 5,000, 10,000, 15,000, and 28,000 Medallion Qualifying Dollars. These can be earned through flying or through credit card spending, with Delta not requiring members to actually fly for Medallion status. Similarly, American Airlines has its general membership tier, its invite-only ConciergeKey status, and four main elite status tiers: Gold, Platinum, Platinum Pro, and Executive Platinum. It uses Loyalty Points as the metric for status, requiring 40,000, 75,000, 125,000, and 200,000 Loyalty Points for each tier. Crucially, however, it's much easier to earn Loyalty Points with American than MQDs with Delta, as the airline essentially awards one Loyalty Point for every eligible base mile earned. Delta awards one MQD for every dollar spent on the base ticket price and associated airline fees on Delta-operated flights, as well as bookings with Delta Vacations. In addition, flights operated by close Delta partners earn MQDs based on a calculation of fare and distance, while SkyMiles co-branded credit cards use their own calculation: the SkyMiles Platinum and Business Platinum cards earn $1 MQD per $20 spent, while the Reserve and Business Reserve seats earn $1 MQD for every $10 spent. SkyMiles & AAdvantage Credit Cards Credit: Markus Mainka | Shutterstock SkyMiles and AAdvantage both offer four personal credit cards, with American Express issuing the SkyMiles co-branded credit cards while Citi issues the AAdvantage co-branded cards. The top-end AAdvantage Executive World Legend Mastercard notably provides unlimited Admirals Club access, whereas the top-end Delta SkyMiles Reserve Amex only grants 15 Sky Club visits annually unless the cardholder reaches $75,000 in annual spend. This is a significant difference. As previously mentioned, the AAdvantage cards provide a quicker path to earning elite status. Both sets of cards offer a variety of benefits, and the choice of which one to choose is largely down to personal preference. However, the benefits of going with SkyMiles are that miles never expire, whereas AAdvantage miles expire after 24 months of account activity. AAdvantage Credit Cards Annual Fee SkyMiles Credit Cards Annual Fee MileUp Card $0 Blue American Express $0 Platinum Select World Elite Mastercard $99 Gold American Express $150 Globe Mastercard $350 Platinum American Express $350 Executive World Legend Mastercard $695 Reserve American Express $650 Business World Elite Mastercard $99 Gold Business American Express $150 Platinum Business American Express $350 Reserve Business American Express $650 In addition, AAdvantage only offers one business card, whereas SkyMiles offers three, making the latter a better choice for this demographic. The AAdvantage Platinum Select World Elite Mastercard has a lower annual fee than the comparable SkyMiles Gold Amex ($99 versus $150). Meanwhile, the AAdvantage Executive World Legend Mastercard has a higher annual fee than the SkyMiles Reserve Amex ($695 versus $650). The two airlines offer sign-on bonuses, usually in the form of bonus miles (although they can include more). Both sets of cards also grant status boosts in the form of extra Loyalty Points/MQDs in some cases, although it's still easier to earn AAdvantage Loyalty Points. Additional Benefits With The Two Airlines Credit: DLeng | Shutterstock American Airlines offers its members multiple additional perks for reaching a certain amount of Loyalty Points. This is solely tied to the number of Loyalty Points reached in a calendar year, with the lowest milestone being 15,000 Loyalty Points. There are also multiple checkpoints, each offering a small variety of benefits that are different from the other milestones. As a whole, the benefits list is quite diverse, allowing AAdvantage members across the board to receive multiple perks throughout the year. Delta Air Lines also offers SkyMiles members additional perks under the 'Choice Rewards' system. However, these are only available to Platinum and Diamond members. Still, the rewards list is extensive for both tiers, with Platinum Medallion members able to choose options such as regional upgrade certificates, an MQD accelerator, bonus miles, a charitable donation, a status gift, statement credit, Starbucks Rewards credit, Delta Vacations credit, a Sustainable Aviation Fuel credit, or a Wheels Up credit. Diamond members get even more choices. Delta is a SkyTeam member, and the SkyMiles program provides reciprocal SkyTeam status for the appropriate tier: SkyTeam Elite for Silver Medallion, and SkyTeam Elite Plus for the higher tiers. American Airlines, on the other hand, is a oneworld member, and oneworld offers three status tiers for loyalty program members. The Emerald tier slots above anything that SkyTeam or Star Alliance offers in terms of benefits. This is a major incentive for AAdvantage members to chase the program's top two tiers, which grant oneworld Emerald status. SkyMiles does not publish an awards chart, as all award flights are priced dynamically, and American AAdvantage also does this for the most part. However, AAdvantage does still use an awards chart for partner-operated flights, publishing estimated starting rates by region. What's more, American allows for upgrades from economy straight to business class (excluding basic economy fares), whereas Delta generally only permits upgrades to the next cabin class. Which Is Better? Credit: BravoKiloPhoto I Shutterstock For some, there are benefits that make SkyMiles a lucrative program, such as miles that never expire, or the wider range of business credit cards. On the surface, however, there are several benefits to going for AAdvantage over SkyMiles, such as the greater upgrade flexibility, oneworld Emerald status, Admirals Club access, the Loyalty Points system, and the generally superior value per mile. Still, two important considerations remain, which might triumph over everything else. The first is that passengers generally consider Delta to offer a better passenger experience. Although the Sky Clubs are harder to access, they're generally considered to be nicer, while nearly all Delta narrowbodies offer seatback entertainment. SkyMiles members aren't necessarily choosing the program over competitors because of the merits of the program, but rather because they want to travel with Delta, and this may be more important to some than certain benefits offered by AAdvantage. However, arguably the most important consideration is location. Regardless of which program's perks are more valuable, this matters little if someone lives in Atlanta, a major Delta hub, or Dallas/Fort Worth, a major American hub. The network and schedules that the dominant airline in a fortress hub offers usually have a much greater effect on which loyalty program to join. Some airports are more competitive, including smaller spokes as well as hubs like New York or Los Angeles, but even then, network and schedule play a major role.
