News reports indicate that Spirit Airlines is in discussions with investment firm Castlelake regarding a potential purchase. If finalized, the deal could help Spirit exit Chapter 11 bankruptcy and stabilize its operations.
Spirit filed for Chapter 11 in August 2025, laying off hundreds of pilots and furloughing at least 1,000 flight attendants as part of its efforts to reduce costs. During bankruptcy, the airline secured over $475 million in investment and implemented a court-approved restructuring plan.
Flight reductions, fleet downsizing and workforce concessions—including $100 million in pay cuts agreed to by pilots and flight attendants—have also been critical to the airline’s ongoing operations, according to news reports.Â
According to CNBC, Minneapolis-based Castlelake has a longstanding presence in aviation finance and in August launched Merit AirFinance, a new aviation lending arm with $1.8 billion in capital.
A potential takeover would likely focus on acquiring Spirit’s physical assets—including aircraft, gates and other equipment—while addressing the airline’s broader financial restructuring. The news comes after merger talks with Frontier Airlines reportedly stalled in late 2025.
While Spirit continues to operate flights nationwide, its future as an independent airline remains uncertain, and the potential Castlelake deal could define the company’s path forward.
