Spirit Airlines shut down all operations early Saturday morning, canceling dozens of flights to and from Orlando International Airport and leaving travelers scrambling to make new arrangements. The airline had been in its second bankruptcy and faced rising jet fuel prices, but had warned of its impending closure for weeks. The closure affected many people in Central Florida, including hundreds of families in town for a cheerleading competition. Some passengers who flew into Orlando on Spirit had to spend thousands on flights home with other carriers, while others had their trips canceled before they even arrived. The shutdown is expected to have a significant impact on operations at Orlando International airport.
