The Sky Clubs are the standard lounge network operated by Delta Air Lines, and access is only granted to Delta’s top customers. Mainly, this includes those who hold a top SkyMiles co-branded credit card, top Medallion members, passengers traveling in Delta One business class, or those who pay for an annual membership.

As has generally been the case with US loyalty programs, these access requirements have changed multiple times in the past, and 2025 saw Delta revise the Sky Club access requirements again. The last major revision to the rules came in February 2025. As expected, Delta tightened up access restrictions to keep more people out of the Sky Clubs.

There were multiple reasons as to why Delta has continued to make Sky Club access harder, and it’s both a commercial as well as an operational decision. With the latest revisions, Delta has also continued its path of becoming a company that rewards frequent spenders rather than frequent flyers, and one that is centered around credit cards.

The Current Access Rules For The Sky Club

Delta sells annual Sky Club memberships to Medallion members, and members must have a same-day boarding pass on a Delta flight or a flight operated by a Delta partner. In addition, passengers traveling in Delta One and in first or business class on a SkyTeam member receive access to the Sky Club. Meanwhile, Delta Gold, Platinum, and Diamond Medallion members receive access if traveling in Delta One or Delta Premium Select on long-haul flights.

Business class passengers traveling with LATAM and WestJet may also enter Sky Clubs. Delta grants 15 Sky Club visits to those holding the Delta SkyMiles Reserve and Reserve Business American Express co-branded credit cards, and unlimited access is granted after $75,000 in qualifying spending during the Medallion year.

Those who hold the American Express Platinum card (but not the Delta SkyMiles Platinum card, which is equivalent to American Express’s Gold card) receive ten visits per year initially. This rises to unlimited access after spending $75,000, while Centurion cardholders may also access Sky Clubs. Before February 2025, Delta granted unlimited Sky Club access to passengers holding the Amex Platinum/Platinum Business and Delta SkyMiles Reserve/Reserve Business cards without a minimum spend.

Meanwhile, customers holding the Delta SkyMiles Platinum and SkyMiles Platinum Business cards lost access in January 2024, which is also when Delta stopped permitting basic economy passengers from entering Sky Clubs. Additionally, the company redefined a visit as entries to any and all Sky Clubs within a 24-hour window.

Why Restrict Sky Club Access?

In 2024, Delta cut Sky Club access from two SkyMiles cards, reserving it only for those with top credit cards, and if you’re booked in basic economy, then you can’t access the Sky Club even with elite status or a top credit card. Later on, the carrier added limits on the SkyMiles Reserve cards and the Amex Platinum cards. These changes are particularly noteworthy because Delta SkyMiles as a whole has devalued miles and removed benefits regularly for the past several years.

Sky Club access is yet another benefit that’s been pared back. However, Delta has an exceptionally strong brand, and SkyMiles is the world’s largest airline loyalty program, which means that there’s high demand for Sky Clubs. Ultimately, the carrier can only build so many Sky Clubs in a single airport, and they became notorious for having long entry lines post-pandemic that stretched outside the lounge itself.

It was a classic mismatch between supply and demand, so Delta has opted to cut demand by making it harder to gain access. While it’s a negative for many passengers, the flip side is that the lounges are no longer overcrowded. This isn’t the only way that the carrier is addressing Sky Club overcrowding, as it’s also been expanding existing Sky Clubs and, more recently, has been opening Delta One lounges throughout the US, which sit above the Sky Clubs.

In addition to addressing overcrowding, restricting access to the Sky Clubs also improves their desirability with customers through perceived scarcity. What’s more, the spending requirement for unlimited Sky Club access means that more passengers will use their co-branded credit cards often to meet the threshold, earning Delta more money.

Credit Cards Come First & Elite Status Is Less Relevant

One striking element of the Sky Club access regulations is that credit card status is more important than Medallion status. While top-tier Medallion members can enter the Sky Club if traveling in Delta One or Premium Select, it’s the SkyMiles Reserve card that’s truly lucrative, since this doesn’t require you to fly in a particular cabin.

This does mean that passengers who hold even Diamond Medallion status can get turned away depending on what cabin they’re in, while a passenger booked in the last row of economy can enter if they hold the appropriate credit card. Delta Air Lines is a powerhouse in the US, but almost none of its money is earned from fares.

Instead, Delta SkyMiles is the carrier’s profit center, because selling millions of miles to program partners is extremely high margin, while demand for Delta’s miles is through the roof. American Express is SkyMiles’ largest partner, and it’s therefore in Delta’s best interest to increase credit card usage and signups since this results in Amex buying even more miles from Delta, boosting profits.

Ultimately, while frequent Delta flyers are valuable to Delta, it’s the Amex cardholders that truly earn Delta huge amounts of money. As such, it’s in the carrier’s best interest to reward loyal customers by offering more benefits in exchange for more credit card spending. In a sense, elite Medallion status can simply be thought of as a small package of additional benefits for frequent spenders, while the Amex credit cards are the real way to get the most out of Delta SkyMiles.

The Reality Of Loyalty Programs Today

There are three main types of loyalty programs: the revenue-based program, the distance-based program, and the segment-based program. Early frequent flyer programs were either distance-based or segment-based, but revenue-based programs have become increasingly popular in recent years because they’re often more profitable than the other types of programs.

American Airlines, Delta Air Lines, and United Airlines all operate revenue-based programs now, but calling them frequent flyer programs is a bit of a stretch today. The number of miles that you earn is directly correlated to how much you spend. Elite status requires thousands of dollars in yearly spend to earn, and as previously mentioned, these don’t actually earn a lot of benefits since this isn’t where the carrier makes money.

Instead, it’s the credit cards that come with real perks, but the cards with the higher annual fees are also the ones with the greatest benefits. Notably, however, credit cards still earn Delta money even if they’re not being used for flights. While Delta Air Lines is the focus of this article, this phenomenon can be seen at all three US airlines.

Elite status is mainly just a small package of benefits, while customers seeking true benefits need to look at co-branded credit cards. Club access is generally limited to those with a membership or a specific top-tier credit card, while Delta and American don’t even have a minimum flight requirement for status. These programs and more have become high-spender programs, rather than frequent flyer programs.

The Future Of US Loyalty Programs

It’s difficult to predict whether Delta will continue to introduce new restrictions on Sky Club access, but it no longer faces as much overcrowding at its Sky Clubs, with the introduction of Delta One lounges possibly having the biggest impact. Notably, Delta has more ways to enter and more rules relating to its Sky Clubs than American or United, which have simpler entry guidelines.

However, American’s Admirals Clubs and the United Clubs are also primarily for credit card holders or those who actively purchase a membership. While all three airlines have focused heavily on credit cards, United Airlines has taken the biggest step by introducing a separate, higher mileage earning rate for co-branded credit cardholders earlier in 2026, while also now granting additional saver award inventory to cardholders.

Whereas carriers have generally been introducing more perks for credit cardholders, United Airlines is essentially penalizing MileagePlus members who do not hold a credit card, diminishing the value of the program for them while boosting value for cardholders. While United is the first airline to be so bold with its focus on credit cards, this is the future.

The money to be earned from credit cards is simply too great, and we’re likely to see United’s contemporaries eventually pursue similar practices. Meanwhile, Delta’s spending requirement for unlimited Sky Club access is an excellent way to boost customer spending, further increasing revenue from selling miles, and it wouldn’t be surprising to see other airlines follow suit.
