The struggles continue for ultra-low-cost Spirit Airlines. Spirit said Friday that it has voluntarily filed for Chapter 11 bankruptcy. It’s the second time the budget carrier has filed for bankruptcy in less than a year. UPDATE: Spirit Airlines Files For Bankruptcy Fox Business has more: The airline’s President and CEO, Dave Davis, wrote in an open letter to customers that the Chapter 11 restructuring process would "ensure the long-term success of our company so we can continue to serve our Guests well into the future." Spirit added that "virtually every major airline has used these tools to improve their businesses and position them for long-term success." The airline first filed for bankruptcy in November after two failed mergers over the previous two years with Frontier and JetBlue. Spirit, an ultra-low-cost airline, has struggled to compete with other major airlines that offer various levels of service and fly to more destinations. The airline assured customers it would continue to operate normally throughout the bankruptcy process, and passengers could use tickets, credits and loyalty points on flights. "Our operation continues as normal, and you can continue to count on us for great value and excellent service," the airline wrote on X. Our operation continues as normal, and you can continue to count on us for great value and excellent service.

Spirit, known for its bright yellow planes and no-frills service, has had a rough ride since the COVID-19 pandemic, struggling to rebound amid rising operation costs and its mounting debt. By the time of its first Chapter 11 filing in November, Spirit had lost more than $2.5 billion since the start of 2020. The airline now carries $2.4 billion in long-term debt, most due in 2030, and reported a negative free cash flow of $1 billion at the end of the second quarter. Friday’s news comes as budget carriers like Spirit are under pressure by bigger airlines, which have rolled out their own low-cost offerings. Spirit, meanwhile, is attempting to tap into a growing market for more upscale travel with its new tiered pricing that includes more perks on the higher end.
