Spirit Airlines' Struggle Shows the Limits of Luxury Plans for Budget Carriers

Spirit Airlines, once known for its low-cost flights and simple travel options, is now facing serious trouble. The airline’s effort to become more “premium” — offering extra comfort and new services — has not worked as planned. Instead, it has revealed how hard it is for budget airlines to survive in today’s travel market.

After coming out of bankruptcy in March 2025, Spirit tried to rebuild its image. It aimed to attract wealthier passengers by adding features like larger seats, snacks, free checked bags, and in-flight Wi-Fi. But just six months later, the Florida-based airline filed for bankruptcy again. This failure shows that moving from a low-cost model to a premium one is not always the solution.

Rising Costs and Fierce Competition

For many years, low-cost airlines like Spirit, Frontier, and Breeze Airways won over travelers by offering cheap tickets. But now, those advantages are fading. Inflation, higher wages, and increased aircraft leasing costs have raised expenses. At the same time, large airlines like Delta, United, and American have started to compete directly by offering their own cheap “basic economy” tickets.

This has left budget airlines squeezed between high costs and shrinking profits. Spirit’s revenue dropped by 20% in the second quarter of 2025, while its operating costs increased sharply. The company reported a $246 million loss in just one quarter. Frontier Airlines, another budget carrier trying a similar approach, lost $70 million during the same period.

Before the pandemic, low-cost airlines had an advantage because their expenses were much lower. In 2019, Spirit’s operating costs were 84% of its revenue. Now, that number has risen to 118%. Frontier’s expenses jumped to 108% of its revenue. These figures show that the low-cost model is under heavy pressure.

The Premium Dream Falls Short

Spirit’s plan was to earn more by offering premium options to travelers who wanted extra comfort. Frontier and Breeze Airways followed similar paths, adding new seating options and bundled perks. However, these changes made operations more complex and costly.

Experts say that by trying to copy big airlines, budget carriers lose what made them special — simple, affordable flying. “Have you seen any low-cost airline that tried to move up and actually survived?” asked John Grant, an analyst at travel consultancy OAG.

Full-service airlines, on the other hand, have more ways to make money, such as business-class seats, cargo services, and partnerships. These help them absorb higher costs better than smaller competitors.

The Big Three Take Over

While budget airlines struggle, the major U.S. carriers — Delta, United, and American — are using their size and resources to take a bigger share of the low-fare market. United’s “basic economy” tickets, for example, now make up 15% of its domestic sales. Their larger aircraft and loyalty programs help them attract both budget and premium travelers.

Frontier CEO Barry Biffle recently complained in a U.S. congressional hearing that big airlines have an unfair advantage because of their loyalty programs. He said smaller airlines often can’t compete on equal terms since they have fewer airport gates and less access to popular routes.

The Branding Problem

Even if Spirit and Frontier offer better seats or free snacks, their biggest challenge is how people see them. For years, these airlines have been criticized for hidden fees and poor service. Many passengers still view them as “cheap but stressful” options.

According to a J.D. Power survey, Spirit and Frontier ranked last in customer satisfaction in 2025. A U.S. Senate report also revealed that both airlines gave $26 million in bonuses to staff to enforce bag policies — which many travelers found unfair.

Michael Taylor, an executive at J.D. Power, explained the issue simply: “People buy from Spirit or Frontier only because they are cheap.”

Both airlines have tried to improve their image. Spirit and Frontier removed many change and cancellation fees and made boarding smoother. Frontier even brought back live phone support for its loyal customers. Yet, many travelers still don’t trust them.

Lesly Simmons, a marketing professional from San Francisco, said she paid twice for a checked bag on a Frontier flight and never got her refund. “I couldn’t imagine leaving an airline like United, which has treated me well, for one that hasn’t,” she said.

Why the Strategy Failed

Spirit’s problem goes beyond just customer service or high costs. The airline tried to become something it was not — a premium carrier. Its passengers mainly look for low fares, not luxury. Adding features like snacks and Wi-Fi only raised costs without changing public opinion.

Frontier and Breeze may face similar challenges if they continue down this path. Their success depends on keeping costs low, not competing head-to-head with major airlines.

The Future of Low-Cost Airlines

Analysts believe the budget airline model can still work — but only if companies focus on efficiency and keep their prices attractive. Flying fewer routes, reducing competition with large carriers, and maintaining simple services could help.

David Neeleman, the founder of Breeze Airways, said that small carriers can still make money by operating nonstop routes that big airlines ignore. This strategy allows them to avoid direct competition while keeping operations lean.

In the end, Spirit’s troubles serve as a warning for other low-cost airlines. Chasing premium travelers might sound appealing, but it can destroy the simplicity that made these airlines successful in the first place.
