Miramar, FL-based Spirit Airlines is an ultra low-cost carrier that went public in 2011. The carrier, previously known as Clippert Trucking Company, changed its name in 1992.

The company, which commenced air charter operations in 1990, provides travel opportunities principally to and from South Florida, the Caribbean and Latin America.

Spirit Airlines' strategy of unbundling its services and offering customers (Frill Control) the option for purchase – ranging from bags and seat assignment to refreshments – has been much appreciated. The unbundled base fares do away with the components that are traditionally included in ticket prices.

Spirit Airlines' primary markets are of three types – large leisure destinations (Orlando, Ft. Lauderdale, Las Vegas, New Orleans, Myrtle Beach, Ft. Myers), large domestic markets (large metropolitan cities) and international destinations (Latin America, Caribbean & northern South America).

The company maintains a young (average of 5.5 years) all-airbus fleet, which operates multiple daily flights to 93 destinations in 15 countries including the United States, Caribbean and Latin America. The fleet is highly fuel-efficient.

The carrier reported operating revenues of $5.36 billion in 2023, up 5.8% year over year. Passenger revenues were up 5.6% year over year owing to the improvement in air-travel demand. Passenger revenues accounted for 98.2% of the top line. The remainder came from non-ticket product purchases.

In March 2024, the merger agreement between JetBlue Airways and Spirit Airlines was cancelled due to anti-trust hurdles. Following the termination, JetBlue will pay Spirit $69 million. Moreover, the termination resolves all outstanding matters pertaining to the deal.

Spirit Airlines' fiscal year coincides with the calendar year.
