Key Takeaways:
The potential collapse of Spirit Airlines threatens to end an era of ultra-low-cost travel, with data suggesting a significant impact on ticket prices for US travelers.
Spirit Airlines' potential liquidation, following a rejected government bailout request, could cause average airfares on its former routes to increase by 14 percent, a Business Insider analysis of aviation data shows. The ultra-low-cost carrier, which has not posted a full-year profit since the pandemic, is facing financial turbulence from rising labor costs, engine problems, and shifting consumer demand.
"When any airline leaves a market, it results in a drop in the supply of seats," Mike Arnot, an airline industry consultant, told Business Insider. "That generally means that airfare will increase, and it doesn't much matter which airline departs a market."
The analysis by Business Insider of Cirium data found that fares rose by an average of $19 on the 90 routes Spirit has already exited between 2024 and 2025. The most extreme case was the Oakland-Newark route, where prices more than doubled from approximately $135 to $288.
The airline's failure would reverse the "Spirit effect," where its presence has historically driven down fares. With Spirit's 7,500 employees and a business model that, despite a $2.8 billion loss in 2025, still influences major carriers, its disappearance would remove a key check on prices, particularly in leisure markets like Florida and Las Vegas.
In a bid to stay airborne, Spirit has approached the Trump administration for a $500 million lifeline. In return, the government would receive a stake of up to 90% in the airline. However, the proposal has been met with skepticism. Kevin O'Leary of "Shark Tank" fame told NewsNation that the bailout is a "really bad idea." It remains uncertain whether the government will intervene to save the airline, which recently saw a proposed merger with JetBlue Airways blocked by regulators.
The data indicates that the financial fallout for consumers could be significant. On the Fort Myers to San Juan route, fares surged by nearly 140 percent, from $92 to $219, after Spirit's exit. Similarly, tickets between Fort Lauderdale and Salt Lake City increased by about 30 percent, or $50. These price hikes illustrate the competitive pressure Spirit exerts on the market. In about 80 percent of cases where Spirit ceased operations, prices increased.
For years, the "Spirit effect" has been a boon for travelers. The entry of the budget carrier into a market often compelled legacy airlines like United Airlines and Delta Air Lines to lower their fares and introduce basic economy options to compete. The potential collapse of Spirit threatens to unwind this dynamic, leading to a market with fewer choices and higher prices. While other factors like fuel costs and demand also play a role, the sharp increases on routes Spirit has abandoned suggest its role as a price anchor is critical.
