The Justice Department preserved Spirit Airlines for competition, then let it die. The DOJ blocked JetBlue’s $4 billion acquisition last year, arguing the merger would hurt consumers. Spirit held just 9% of the market. But the antitrust move left the carrier alone against surging jet fuel prices and rising pilot wages, with only three weeks of cash remaining.
Spirit’s unbundling model - charging for water and carry-ons to keep base fares low - forced industry-wide price cuts. Whenever it entered a new airport, competitors dropped fares by up to 10%. The airline brought first-time fliers and working-class families ‘off the sidelines,’ acting as a crude tool for democratizing travel.

The model had no buffer. Major airlines cannibalized Spirit with their own basic economy seats, while offering better networks and backup options. Spirit lacked a $2,000 business class cabin to subsidize its cheap seats. When fuel costs spiked due to the Iran war and labor costs rose, its edge vanished.
Peter St. Onge argues regulators issued a death sentence to the company driving down prices for low-income travelers. The $400 million annual tax burden and fuel cost spike pushed the low-cost model past its breaking point. A proposed $500 million government lifeline collapsed after lenders refused the terms.

The industry is pivoting away from the budget traveler. Major airlines now invest in lounges, loyalty programs, and premium seats. Allegiant Air survives by avoiding direct competition - 75% of its routes have no rival carriers. Experts predict fares will rise, partly from higher fuel costs but also because major carriers have less incentive to compete aggressively for basic economy.
The Saturday morning shutdown stranded 17,000 employees and tens of thousands of passengers. The era of the ultra-low-cost carrier is over.
