Spirit Airlines operates an extensive network throughout North, Central, and South America and the Caribbean. While the ultra-low-cost carrier (ULCC) operates several flights with shorter distances with its all-Airbus fleet, it has some notable lengthy routes. This allows Spirit to have a formidable presence on both coasts and is a result of its dramatic growth within the past decade. Despite recent headwinds, the airline continues evolving its route network to be appropriate to its business model and to best serve its passengers.
