Spirit Airlines (NK)
Spirit Airlines (NK) is a U.S.-based ultra-low-cost carrier headquartered in Dania Beach, Florida. Founded in 1983, Spirit has grown to serve over 90 destinations across the United States, the Caribbean, Central America, and South America. The airline operates on a no-frills model designed to keep base fares low while allowing passengers to choose and pay for the services they want. Its business strategy centres around efficiency, route expansion, and affordability for leisure travellers and price-sensitive customers seeking cheap flights on Spirit Airlines.
About Spirit Airlines
Spirit Airlines began operations as Charter One, a travel company offering vacation packages. In 1992, it rebranded as Spirit Airlines and transitioned into scheduled passenger service. By the late 1990s, it had established routes across Florida and the Northeastern U.S.

In the early 2000s, Spirit expanded into Latin America and the Caribbean, targeting high-demand vacation routes. In 2007, the airline shifted its focus to the ultra-low-cost carrier model, separating fares from services and charging passengers for extras like carry-on bags, seat selection, and food.
Spirit went public in 2011, gaining financial flexibility to expand its fleet and route network. After facing financial challenges and operational disruptions in the early 2020s, Spirit filed for Chapter 11 bankruptcy in 2024. It restructured and resumed growth in 2025 with renewed investor backing and updated aircraft orders.
Business Model and Structure
Spirit uses a point-to-point network rather than a traditional hub-and-spoke model. Flights often connect cities directly rather than routing through large hubs. This reduces layovers and operational costs.
The airline keeps base fares low by removing all non-essential services from the ticket price. Passengers pay only for what they use—whether that’s baggage, seat upgrades, or early boarding. This model makes it easier for travellers looking to book flights on Sprit Airlines without hidden costs.
Spirit’s revenue is balanced between fare collection and ancillary fees, which include baggage charges, seat assignments, onboard food, and change fees.
