Why Are Credit Card Companies Building Airport Lounges?
American Express is not an airline.
Neither is Chase.
Neither is Capital One.
Yet all three have put their names on some of the most desirable spaces inside airports.
They build lounges.
They serve food.
They hire bartenders.
They install showers, workspaces and comfortable chairs.
That is a strange business for a financial company to be in.
Banks issue cards and move money.
So why are they competing over airport real estate?
The answer has less to do with free drinks than it appears.
The lounge is becoming the physical layer of a financial relationship.
A Credit Card You Can Walk Into
Most of a credit card relationship is invisible.
You see a card in your wallet.
A number on your phone.
Points on a screen.
Then you arrive at an airport and suddenly that financial product becomes a place.
There is a door.
A restaurant.
A bar.
Someone checks your card.
And the bank's name is on the wall.
American Express has Centurion Lounges.
JPMorgan Chase has Sapphire Lounges.
Capital One has Capital One Lounges.
Financial companies are turning products that once lived in wallets into hospitality experiences.
And they are doing it for a valuable reason:
the customer.
Premium Cards Are Fighting for Affluent Travelers
Premium credit cards can carry extraordinary annual fees.
The U.S. American Express Platinum Card currently costs $895 a year.
One of its major benefits is access to the American Express Global Lounge Collection, which includes more than 1,550 lounges across more than 500 airports in 140 countries.
But there is an important distinction.
American Express does not operate all 1,550 lounges.
The network combines its own Centurion Lounges with partner lounges and networks such as Priority Pass.
The scale still tells us something important.
Airport access has become a major part of the premium credit card proposition.
And the customers these cards are chasing can be especially valuable.
Morgan Stanley says premium travel cards are strategically important to banks because they help attract and retain affluent consumers.
These customers travel.
They buy flights.
They book hotels.
They eat at restaurants.
They spend internationally.
And they may put large amounts of spending through a single card.
A lounge gives them another reason to keep that card.
The Business Behind Travel Cards Is Already Huge
This isn't a small corner of banking.
Morgan Stanley estimates that airline and hotel co-branded travel credit cards currently generate roughly:
$24 billion in annual revenue.
Its base case has that figure reaching approximately:
$60 billion by 2035.
Its most optimistic scenario reaches $100 billion, although that is a bull case rather than the base forecast.
Those numbers help explain why banks are willing to spend heavily on rewards, travel benefits and airport lounges.
A premium card isn't valuable only because someone pays an annual fee.
The bank can build a much larger financial relationship around that customer.
And the lounge sits inside that relationship.
Then There Is the Airline
This is where the business gets much bigger.
Airline miles look like rewards.
But behind those miles is a large financial relationship between airlines and banks.
Take Delta Air Lines.
Delta has a long-standing co-branded credit card partnership with American Express.
Behind the scenes, Delta sells miles and other benefits to partners such as Amex.
In 2025, Delta received:
$8.2 billion
in remuneration from American Express.
That was up about 11% from the previous year.
Delta says it expects that figure to reach approximately $10 billion over the next few years.
Think about that number.
$8.2 billion.
This isn't revenue from selling airline tickets to passengers.
It comes from a commercial relationship between an airline and a financial company built around loyalty, credit cards and customers.
Delta also reported more than 1 million co-brand card acquisitions in 2025, its fourth consecutive year above that level.
Suddenly, the airport lounge looks different.
It isn't just a room with free food.
It sits on top of a very large financial ecosystem.
Airlines Sell More Than Flights
The traditional airline business is easy to understand.
Sell a ticket.
Fly the passenger.
Collect the money.
But modern airlines have another valuable asset:
their customers' loyalty.
An airline can sell miles and benefits to a bank.
The bank can use them to reward cardholders.
The airline gets paid.
And the customer has another reason to remain connected to both companies.
Delta reported that approximately 35 million award tickets were used in 2025, with award travel representing 12% of its revenue miles flown.
This turns everyday spending into something connected to future travel.
Groceries today can become miles toward a flight tomorrow.
A restaurant bill can become points.
A hotel stay can generate another reward.
The credit card connects spending outside the airport with what happens inside it.
And the lounge gives that otherwise invisible relationship a physical home.
Why the Airport?
A bank could build a beautiful lounge almost anywhere.
But airports have something unusual.
They naturally concentrate many of the customers premium travel cards want.
Frequent travelers.
Business travelers.
People buying flights.
People booking hotels.
People spending internationally.
People willing to pay for convenience.
Not everyone inside an airport is wealthy, of course.
But premium travel puts banks repeatedly in front of the kind of higher-spending customers they are trying to attract and retain.
In that sense, the airport can function almost like a high-value customer filter.
That is an interpretation, not a term banks themselves use.
But it helps explain why some of the world's largest financial institutions want physical space inside terminals.
Points Are Easy to Copy. Space Is Harder.
Credit cards have a problem.
Rewards can be copied.
One bank offers more points on travel.
Another increases its bonus.
One offers a hotel credit.
Another offers a bigger one.
The numbers can keep changing.
Physical infrastructure is different.
Good airport space is limited.
A lounge requires agreements, construction, staff, food, operations and enough locations to make the network useful.
And once travelers build habits around a particular lounge network, the benefit becomes more tangible than another number on a rewards page.
This helps explain the rise of proprietary lounges.
American Express doesn't only want its customers to enter someone else's lounge.
It has Centurion.
Chase has Sapphire.
Capital One has its own name above the door.
Morgan Stanley has noted that as competition in travel cards intensifies, issuers may increasingly build their own travel offerings, including proprietary airport lounges and non-co-branded travel products.
The bank is no longer simply buying access to someone else's experience.
It can create the experience itself.
The Lounge Doesn't Have to Make Money by Itself
There is an important distinction here.
We don't know the return on investment of an individual Centurion, Sapphire or Capital One lounge.
The companies do not publicly disclose enough information to calculate whether the food, drinks, staff and airport space of a particular lounge directly generate a profit.
But that may be the wrong question.
Imagine a lounge helps convince someone to keep a premium card.
That customer continues spending on the card.
They use travel services.
They remain a customer for years.
The economic value created by the lounge may appear somewhere else in that relationship.
The lounge doesn't have to be the business.
It can make the relationship more valuable to the business.
Calculating the price of the food and comparing it with the annual fee misses much of what is happening.
Southwest Is Joining the Game
One of the clearest signs of how important this model has become comes from an airline that historically stayed away from it.
Southwest Airlines built its reputation around a simpler, lower-cost flying experience.
For decades, airport lounges were not part of that model.
That is changing.
In September 2026, Southwest announced plans for its first-ever airport lounges.
The first four are planned for:
Austin.
Baltimore.
Honolulu.
Nashville.
And Southwest isn't doing it alone.
It is partnering with JPMorgan Chase.
A new Chase-issued premium Southwest credit card is planned for 2027 and will provide access to the lounge network, with the first lounges expected to begin opening in late 2027.
Southwest is trying to attract more premium travelers and broaden its sources of revenue.
The interesting part is the combination.
An airline.
A bank.
A premium card.
A loyalty program.
And now a physical room inside the airport.
The pieces that once looked like separate businesses are becoming part of the same customer relationship.
Who Owns the Traveler?
Banks want valuable customers.
Airlines want loyal passengers.
Banks want card spending.
Airlines can sell miles and benefits to banks.
Hotels want bookings.
Travel platforms want transactions.
All of them can benefit from working together.
But they are also competing for something.
The relationship with the traveler.
As co-branded cards become more valuable, airlines and hotel groups can demand more from their financial partners.
Morgan Stanley expects airline and hotel partners to gain somewhat more bargaining power as the industry grows.
Meanwhile, banks are building their own travel platforms, experiences and lounges.
So the competition is no longer simply:
American Express vs. Chase vs. Capital One.
It is also about who controls the customer relationship before, during and after the trip.
That makes the airport lounge much more interesting than it first appears.
Credit Cards Are Becoming Places
Credit cards used to compete inside your wallet.
Now they compete inside airports.
A bank can still offer points.
Cash back.
Travel credits.
Insurance.
But now it can also build a door you want to walk through.
Inside that door, an invisible financial product becomes physical.
The food is real.
The drinks are real.
The furniture is real.
The expensive airport space is real.
But they may not be the most valuable things inside the room.
The most valuable thing may be sitting in one of the chairs.
The customer.
BEYOND THE OBVIOUS.
