Answers: What caused the collapse and shutdown of Spirit Airlines?

• Spirit Airlines business model
• Ultra-low-cost carrier economics
• Airline mergers and antitrust law
• Impact of COVID-19 on aviation
• Pratt & Whitney engine recalls

What it concludes

• Spirit Airlines found a highly successful niche with an ultra-low-cost model, growing passenger counts from under 7 million in 2010 to nearly 34 million in 2019 while turning a profit each year.
• Post-COVID recovery proved difficult for Spirit as mainstream airlines lowered economy prices and passengers increasingly elected to pay for premium offerings, eroding Spirit's low-cost market advantage.
• Pratt & Whitney engine manufacturing contamination issues forced Spirit to ground up to 40 aircraft and incur massive lease costs without sufficient compensation.
• The Biden DOJ successfully blocked both the Frontier and JetBlue merger proposals on antitrust grounds, destroying Spirit's exit strategies and accelerating its financial collapse.
• Spirit Airlines ceased all operations on May 2, 2026, resulting in 17,000 job losses and ending a 34-year legacy of budget air travel.
