On December 9, 2002, UIL Corp, the parent company of United Airlines, filed for the largest aviation bankruptcy in U.S. history. This was due to a combination of record losses, high costs, and a slump in travel demand. The situation was exacerbated by a labor dispute that increased compensation costs, a failed merger with U.S. Airways, the economic impact of the September 11 attacks, and the denial of a $2 billion government-backed loan. United Airlines, the largest of the 28 business units involved, listed $23 billion in assets against $21 billion in debt. The bankruptcy process was complex, involving numerous business units, partnerships, and creditors, and took 1150 days to resolve. Despite the challenges, the bankruptcy allowed United Airlines to restructure and emerge as a more efficient airline, ultimately aiding its recovery and growth, especially during the 2020 pandemic. The video also notes that WR Grace surpassed United's bankruptcy duration, taking 12 years to resolve its own proceedings.
