About
Spirit Airlines is one of the largest ultra-low-cost carriers (ULCC) in the United States, headquartered in Miramar, Florida. Founded in 1980 as a trucking company, Spirit transitioned to passenger aviation in 1992 and pioneered the "Bare Fare" unbundled pricing model in the US market.
Spirit operates an all-Airbus fleet serving over 90 destinations across the United States, Caribbean, and Latin America. The airline's business model strips the base fare to its minimum, with passengers paying separately for carry-on bags, checked bags, seat selection, and refreshments. For travelers with flexibility and minimal luggage, Spirit can offer significant savings over legacy carriers. For those requiring bags and seat selection, always compare total costs.
Spirit is not a member of any airline alliance and does not have codeshare partnerships with other airlines.
