Spirit Airlines

Spirit Airlines is an American ultra‑low‑cost carrier headquartered in the United States that provides scheduled passenger air transportation. The airline sells base fares at low prices and generates additional revenue through charges for optional services such as baggage, seat selection, and onboard refreshments. Its route network focuses on domestic flights within the United States and international services to destinations in the Caribbean, Mexico, Central America, and South America. The company primarily serves leisure and price‑sensitive travelers seeking affordable air travel options.

Spirit Airlines distinguishes itself from legacy carriers by adhering to a high‑density, single‑class aircraft configuration that maximizes seat count and reduces operating costs per seat. The airline maintains a fleet composed mainly of Airbus A320 family jets, which supports its strategy of simplicity and fuel efficiency. Spirit’s business model emphasizes strict cost control, rapid aircraft turnaround times, and a reliance on ancillary fees to supplement ticket revenue. These characteristics have positioned Spirit as a notable competitor in the low‑cost segment of the North American aviation market.

In March 2021 Spirit Airlines suffered a ransomware attack carried out by the Nefilim group, during which attackers exfiltrated over 40 gigabytes of data, including financial records and personal customer information from ticket purchases, and subsequently published more than 33,000 files online. The incident highlighted the airline’s exposure to cyber threats targeting sensitive passenger and operational data. Following the breach, Spirit undertook efforts to notify affected individuals and to strengthen its information security controls.
