There are few things that can elevate your travels more than relaxing in an airport lounge ahead of your flight.

However, there are trade-offs when it comes to lounge access.

For starters, getting in usually isn’t free. Guest policies can also vary, and some access methods limit the number of visits. And, of course, just how many lounges you can get into plays a major role in determining the best strategy for you.

As part of TPG’s 2026 best airlines report, we took a deep dive into these very characteristics to identify which airline offers the best bang for your buck — and here’s what we found.

How TPG evaluates our airline lounge access rankings

To help analyze the various options, we started with three overarching questions:

• What’s the most cost-effective way to access the largest number of lounges with each airline?
• Where are the lounges you can access — based on both the number of unique airports and number of lounges?
• What restrictions (or flexibility) come along with said access?

Once we compiled all the data across airlines, we took each airline’s lounge footprint, factored in the access policies and calculated an adjusted cost-per-airport and cost-per-lounge for the primary access method.

In the end, one airline rose to the top — with another nipping on its heels.

Best overall: American Airlines

American Airlines took the top score in the lounge category thanks to the Citi® / AAdvantage® Executive World Elite Mastercard® (see rates and fees). This card’s $595 annual fee includes a full Admirals Club membership, granting wide-ranging lounge access to the carrier’s own Admirals Clubs, Alaska Lounges, Qantas Lounges and even select Oneworld lounges when flying American or a partner airline.

All in, you have lounge access in more than 80 global airports across more than 100 individual locations.

Beyond the footprint, the Citi Executive Card features a pair of really appealing policies:

• Guest policy: You can access these lounges with either two guests or your immediate family (spouse or partner and dependent children under the age of 18).
• Authorized user access: Authorized users on the card get their own access, though it’s limited to Admirals Club locations. This even includes the same guest privileges as the primary cardholder. You can add up to three for an additional $175 in annual fees, and it’s $175 for each one after that.

These pushed American above its counterparts.

Most extensive network: Delta Air Lines

However, nipping on American’s heels was Delta Air Lines, TPG’s overall best airline for the eighth straight year. The carrier already has a larger footprint of its own lounges compared to any of its competitors. However, since we also analyzed the access policy on the Delta SkyMiles® Reserve American Express Card, this expanded the list significantly.

That’s because you can also access the following lounges when flying a Delta flight booked with your Delta Reserve Card:

In the U.S. alone, this gives you nearly 50 airports and close to 90 individual lounges.

However, the card’s access policies blunt the effectiveness of this huge network. For starters, you’re only eligible for 15 annual visits to Sky Clubs (unless you spend $75,000 on the card in a calendar year). In addition, you get only four guest passes per year — any additional guests will cost you $50 each. Finally, you aren’t eligible for lounge access on a basic economy ticket.

Nevertheless, if you frequently travel alone and don’t need more than 15 Sky Club visits in a year, the Delta Reserve Card may be a great option.

Best for elites and big spenders: United Airlines

While spending on the Delta Reserve can unlock unlimited Sky Club visits, United Airlines may actually be a better option for elite travelers and big spenders. That’s because the United Club℠ Card (see rates and fees) gives a pathway to a much broader set of lounges for these individuals.

When you reach Premier Gold status (or higher) or spend $50,000 on the card in a calendar year, you unlock United Club All Access membership. This is valid for the rest of the calendar year in which it’s earned and the entire following calendar year. Beyond United Clubs, this gives you access to over 140 additional lounges across close to 60 international airports.

In addition, the United Club Card allows the primary cardholder to bring in one adult guest and dependent children under the age of 18, so this can be quite valuable for family travelers.

Other highlights from the report

There were some other interesting items that came out of our analysis.

Credit cards usually offer the best access

In most cases, the best access method was the carrier’s premium credit card — but that wasn’t true across the board.

Alaska Airlines is a great example. The Atmos™ Rewards Summit Visa Infinite® credit card provides two Alaska Lounge day passes each quarter, and while it has a comparatively low annual fee of $395, it’s not the best Alaska option for extensive lounge access. That’s the Alaska Lounge+ membership, which is $795 and includes unlimited access to Alaska Lounges plus nearly 90 partner locations.

JetBlue Priority Pass access

First, the JetBlue Premier Card was actually the best for non-brand lounge access among all of the access methods we reviewed. Even though there’s only a single JetBlue BlueHouse open right now — at New York’s John F. Kennedy International Airport (JFK) — the card also gives you Priority Pass Select membership, a relative rarity on cobranded airline cards.

The information for the JetBlue Premier Card has been collected independently by The Points Guy. The card details on this page have not been reviewed or provided by the card issuer.

Using the Citi Executive Card for Alaska lounge access

In addition, Alaska travelers may be best served by the Citi Executive Card, especially since it’s $200 cheaper than an Alaska Lounge+ membership. The lounge footprint is almost identical, and since Alaska is part of Oneworld, you can still access all of the applicable locations, whether you’re flying American, Alaska or another alliance carrier.

Lower-budget options for lounge access

Finally, there are many alternative ways to access these lounges, so you may have a lower-cost option available.

For example, both the Citi Strata Elite℠ Card (see rates and fees) and the Citi® / AAdvantage® Globe™ Mastercard® (see rates and fees) include four Admirals Club passes each year — and the Citi AAdvantage Globe card currently has an limited-time welcome offer of 90,000 bonus miles after $5,000 in purchases in the first four months of account opening.

You also receive a pair of United Club passes on the United℠ Explorer Card (see rates and fees) each year.

Crunch the numbers to ensure you can justify the high annual fee of a premium card or a paid lounge membership.

Bottom line

We overhauled the lounge access methodology portion of our 2026 list of the best airlines in the U.S. — and the data was fascinating. While American scored the highest overall, Delta’s lounge network was the most extensive, especially when considering the list of Amex and Escape lounges that Delta Reserve cardholders can access.

Of course, much of this depends on your unique situation, so be sure to take your personal travel habits into account when deciding on the best way to unlock lounge access for your next trip.
