Spirit Airlines in Talks for Acquisition Amid Bankruptcy
Spirit Airlines explores new paths as bankruptcy proceedings unfold
New York, NY – In a significant development within the aviation industry, Spirit Airlines is currently engaged in discussions with Castlelake, an investment firm, regarding a potential acquisition. This move comes as the low-cost airline seeks to navigate its way out of its second Chapter 11 bankruptcy filing in less than a year, following a failed merger attempt with Frontier Airlines.
The ongoing restructuring efforts at Spirit highlight the resilience of businesses within the aviation sector, particularly as operators strive to adapt under challenging economic circumstances. This dialogue between Spirit and Castlelake exemplifies how strategic investment and entrepreneurial innovation can pave new paths for recovery and growth in the face of adversity.
Background on Spirit Airlines’ Financial Challenges
Spirit Airlines filed for Chapter 11 bankruptcy protection in August 2025, marking its second filing within a year. The airline attributed its financial woes to several factors, including increasing debt, unsuccessful merger agreements, and heightened competition in the sector. As a strategic response, Spirit is actively looking at reducing its fleet to achieve stabilization.
To aid in its restructuring, Spirit Airlines secured a boost in funding, amounting to $50 million in emergency financing in mid-December 2025. This financial shot in the arm is designed to support the airline’s efforts toward a standalone reorganization plan or to facilitate a strategic transaction.
Castlelake’s Role in Aviation Finance
Castlelake, headquartered in Minneapolis, has been a significant player in aviation finance for several years. In August 2025, the firm launched Merit AirFinance, an aviation lending arm equipped with $1.8 billion in deployable capital. Since 2020, Castlelake has successfully deployed over $5 billion to airlines and leasing companies, showcasing its commitment to bolstering the aviation sector in challenging times.
Previous Merger Discussions
Before engaging with Castlelake, Spirit Airlines had initially entered into discussions with Frontier Airlines about a potential merger. However, those negotiations did not culminate in a finalized agreement. Frontier Airlines previously attempted to merge with Spirit but withdrew four years ago due to a competing offer from JetBlue Airways.
Current Status of Bankruptcy Proceedings
As of now, there have been no disclosures regarding any transactions involving Castlelake or other entities within the court filings related to Spirit Airlines’ ongoing bankruptcy proceedings. The case continues to progress, with a claims bar date set for January 27, 2026, as stakeholders monitor the outcomes of these discussions carefully.
