Southwest Airlines Partners With Chase to Launch Co-Branded Airport Lounges

Southwest Airlines is pushing ahead with plans to open its first premium airport lounges, and the carrier has picked a familiar financial partner to help make it happen. The airline confirmed it will co-brand the lounges with Chase, the bank behind its co-branded credit card portfolio.

The move marks a significant departure for a carrier that built its reputation on a no-frills, single-class cabin experience. For decades, Southwest avoided the trappings of legacy competitors like Delta, American, and United, all of which operate extensive lounge networks at major hubs. That approach is changing as Southwest overhauls nearly every part of its passenger experience.

What Southwest has said so far

Southwest executives disclosed the lounge plans during recent investor communications, framing the project as part of a broader push to attract higher-spending travelers. The airline has not yet named the airports where the lounges will open, nor has it shared a firm timeline for when the first location will welcome guests.

What is clear is that Chase will play a central role. The bank already issues Southwest's Rapid Rewards credit cards, and the co-branded lounge concept follows a pattern set by other carriers. Southwest charges an annual fee of $299 for its Southwest Rapid Rewards Priority Card. Chase operates its own Sapphire Lounge network for premium cardholders, and it partners with United on the Chase-branded Club spaces at select airports.

Why now

Southwest is in the middle of the largest strategic shift in its history. The airline is ending open seating after more than 50 years, introducing assigned seats and a premium extra-legroom section. It has also announced red-eye flights, checked bag fees for most customers, and partnerships with international carriers to feed connecting traffic.

Activist investor Elliott Investment Management pushed for many of these changes after taking a large stake in the company in 2024. The lounge announcement fits the pattern of moves designed to lift revenue per passenger and appeal to business travelers who have historically favored legacy airlines.

Southwest CEO Bob Jordan has framed the changes as necessary to meet evolving customer expectations. The carrier has struggled with profitability compared to its larger peers, and premium products are one of the most reliable ways for airlines to grow margins.

The Chase connection

Chase has spent the last several years building out its own airport lounge footprint under the Sapphire Lounge by The Club brand. Locations already operate in cities including New York, Boston, Phoenix, San Diego, Las Vegas, and Hong Kong, with more planned.

A co-branded arrangement with Southwest would likely give Chase Sapphire Reserve cardholders and top-tier Southwest credit card customers access, though the exact eligibility rules have not been announced. The partnership also gives Southwest a financial backer for what is typically an expensive undertaking. Building and operating an airport lounge involves securing scarce terminal real estate, high buildout costs, and ongoing staffing and catering expenses.

How this compares to competitors

Delta operates more than 50 Sky Clubs across its network and recently opened its higher-end Delta One Lounges for international premium passengers. American Airlines runs Admirals Clubs and Flagship Lounges, and United has its United Club and Polaris Lounge network. All three carriers use lounges as a key selling point for premium fares and elite frequent flyer status.

Southwest, by contrast, has never operated a lounge of any kind. Its terminal presence at most airports consists of gate areas and ticket counters. Adding lounges would require the carrier to secure space at airports where it already has a large operation, such as Dallas Love Field, Chicago Midway, Baltimore/Washington, Denver, Las Vegas, and Houston Hobby.

Questions that remain

Several details are still unclear. Southwest has not said whether lounge access will be tied to a specific fare class, a new elite tier, a credit card, or a paid membership. The airline is introducing a premium seating section on its aircraft, and lounge access could be included in that product bundle.

The timing of the first opening is another open question. Building a lounge from scratch typically takes 18 to 24 months once a location is secured, meaning travelers likely will not see a Southwest lounge before late 2027 or 2028 at the earliest.

There is also the question of how existing Southwest loyalists will react. The airline's core customer base has long valued its straightforward, low-cost approach. Some frequent flyers have voiced frustration on social media about the pace of changes, from bag fees to seat assignments. Adding lounges may reinforce the sense that Southwest is drifting toward the legacy model it once defined itself against.

For now, the airline is signaling that the transformation will continue. The Chase-branded lounges are one more piece of a very different Southwest taking shape.
