Spirit Airlines, which plans to exit Chapter 11 bankruptcy proceedings early this summer, has warned that rising fuel prices driven by war in the Middle East could negatively impact its business prospects. The company listed the rising price of fuel as one of the more prominent risks confronting the company as it prepares to transition into a smaller airline with a lighter debt load. The airline's fleet also looms as a factor as it reduces its fleet by shrinking its Airbus jetliners and ending lease agreements on some older planes. Other challenges facing Spirit include increased competition from larger and stronger competitors, which have seen Spirit lose customers and leave Spirit out of various U.S. and foreign markets.
