WEST PALM BEACH, Fla. (AP) — Spirit Airlines has announced it is going out of business after 34 years. The ultra-low-cost airline known for its bright yellow planes and deep discount fares said Saturday it has started winding down operations. It said all its flights have been canceled and customer service is no longer available. The airline had been struggling financially since the COVID-19 pandemic, weighed down by rising costs and debt. Efforts to secure a government bailout failed, leaving about 17,000 jobs at risk. Spirit’s closure could impact budget-conscious travelers, especially in areas like Las Vegas and Florida, where the airline had a significant presence.
