Spirit Airlines has filed for Chapter 11 bankruptcy protection for the second time in just a few months, facing ongoing financial challenges that have prompted the low-cost airline to seek court protection once again. With an estimated $8 billion in debt, the airline intends to continue its operations while navigating a tumultuous financial landscape. The decision comes as Spirit Airlines struggles to implement a successful turnaround strategy, leading to concerns about its long-term viability. In light of the bankruptcy filing, Spirit has issued an open letter to guests and reassured them that flights will continue as scheduled, despite fears of potential closure and its precarious financial situation.
