Spirit Airlines is a major American ultra-low-cost carrier known for its budget-friendly travel options. Founded in 1983, Spirit Airlines has grown to serve destinations across the United States, Latin America, and the Caribbean. The airline is headquartered in Miramar, Florida, and operates a fleet primarily composed of Airbus A320 family aircraft. Spirit is recognized for its distinctive yellow and black livery and its "Bare Fare" model, which allows travelers to customize their flying experience by adding on only the services and amenities they desire, such as bags, seat assignments, and refreshments, for additional fees. This a la carte approach to flying is designed to keep base ticket prices low, making air travel more accessible to a broader audience. Spirit Airlines continues to expand its route network, offering frequent flights and appealing to travelers seeking a no-frills, cost-effective way to reach their destinations.
