Spirit Airlines

About Spirit Airlines

Spirit Airlines is the United States' leading ultra-low-cost carrier (ULCC), built on a single overriding principle: offer the absolute lowest possible base fare and let travelers pay only for the extras they actually want. Founded in 1983 as Charter One Airlines, Spirit transitioned to scheduled service and rebranded as Spirit Airlines in 1992, ultimately adopting the ULCC model in the early 2000s. Today, Spirit is headquartered in Miramar, Florida, and operates an all-Airbus narrowbody fleet from focus cities including Fort Lauderdale-Hollywood (FLL), Orlando (MCO), Las Vegas (LAS), Dallas/Fort Worth (DFW), and Detroit (DTW).

Spirit serves over 85 destinations across the United States, Latin America, and the Caribbean, with a particular emphasis on leisure and vacation markets. The airline's distinctive yellow-and-gray aircraft are a familiar sight at airports serving beach destinations, theme parks, and major American cities. Spirit's model requires understanding — the advertised "Bare Fare" includes the seat and not much else — but travelers who understand and prepare for the à la carte pricing structure can achieve some of the lowest total travel costs of any U.S. carrier, particularly for short trips without checked bags.

Spirit Airlines Route Network

Spirit's network is strategically focused on high-demand leisure routes where price-sensitive travelers represent the largest segment of demand. Fort Lauderdale-Hollywood International serves as Spirit's primary hub and the largest point of operation, with extensive service to Caribbean islands including Puerto Rico, Jamaica, the Dominican Republic, the Bahamas, Aruba, Curaçao, and more. From Fort Lauderdale, Spirit also operates routes to Colombia, Costa Rica, Panama, Peru, and other Latin American destinations, serving the large Latin American diaspora community in South Florida as well as American travelers seeking affordable international escapes.

Domestically, Spirit connects major U.S. cities on popular leisure routes — Las Vegas to Seattle, Dallas to Los Angeles, Orlando to Chicago, and Atlanta to Newark, among many others. The airline's point-to-point model means passengers often fly directly between cities without connecting through a hub, which can result in shorter overall travel times compared to connection-dependent legacy carrier itineraries. Spirit has consistently expanded its domestic network by identifying underserved markets where stimulating lower fares generates new travel demand that would not exist at higher price points.

The Bare Fare Model Explained

Spirit's Bare Fare is the foundation of its pricing strategy and the key to understanding how to maximize value when flying Spirit. The Bare Fare includes your seat and a small personal item (approximately the size of a purse, backpack, or laptop bag) that fits under the seat in front of you — and nothing else beyond the flight itself. Carry-on bags, checked baggage, seat selection, printed boarding passes, and in-flight snacks and beverages are all available for purchase as à la carte add-ons at prices set at the time of booking.

The smartest way to fly Spirit is to pack light and plan ahead. Passengers who carry only a personal item that fits under the seat — a well-organized backpack, for example — and who check in online in advance can often fly for the base fare with zero additional fees. Travelers who add a carry-on or checked bag should do so during the booking process, as bag fees are significantly lower when added at booking compared to adding them at the airport or at check-in kiosk. Spirit's website clearly publishes its current fee schedule, and CheapFareFreak provides guidance on estimating the total cost of your Spirit itinerary including typical add-ons.

Big Front Seat

Spirit's Big Front Seat is one of the most unique seat products available on a U.S. ultra-low-cost carrier. Located in the first two rows of the cabin, Big Front Seat features a much wider seat (approximately 18.5 inches wide versus 17.75 inches for standard seats), significantly more legroom (36 inches of pitch versus 28-32 inches in standard rows), and no middle seat between the two seats in each row. The Big Front Seat essentially delivers a domestic business-class width and legroom experience at prices that are often a fraction of legacy carrier first-class fares on comparable routes.

Big Front Seat does not include complimentary food, beverages, or checked bags, but it offers a genuinely premium physical experience that many travelers find worthwhile, particularly on longer Spirit routes. When Big Front Seat is priced modestly above standard fares, it represents exceptional value, particularly for taller passengers or those who simply prefer more personal space during the flight.

Free Spirit Loyalty Program

Free Spirit is Spirit Airlines' frequent flyer program, offering points for purchases made on Spirit flights and through partner programs. Points are earned based on the dollar amount spent and can be redeemed for award flights on Spirit with no blackout dates. The program has two elite tiers — Silver and Gold — earned by accumulating qualifying points within a year. Elite benefits include bonus point earnings and priority boarding.

Spirit's co-branded Bank of America credit card accelerates Free Spirit point earning on everyday purchases and includes a companion fly-free benefit that can deliver significant savings for travelers who fly Spirit regularly with a companion. Points can be used toward any available Spirit seat, including the Big Front Seat, and are most valuable when redeemed for higher-cost itineraries. Free Spirit miles expire after 90 days of account inactivity, so it is important to maintain engagement with the program through purchases or partner activity.

Spirit Airlines Fleet

Spirit operates an all-Airbus narrowbody fleet consisting of A319, A320, and A321 family aircraft. The fleet is among the youngest in the U.S. airline industry, with Spirit having made a strategic decision to operate new aircraft for their fuel efficiency, reliability, and reduced maintenance costs — savings that directly enable lower base fares. Spirit has also ordered Airbus A320neo and A321neo aircraft, which offer even greater fuel efficiency through new-generation CFM LEAP engines, further strengthening the airline's cost advantage over competitors.

Tips for Flying Spirit Airlines on a Budget

To get the most out of Spirit Airlines, follow these key strategies. First, pack exclusively into a personal item that fits under the seat in front of you to avoid all bag fees. A 40L backpack sized to Spirit's personal item dimensions is the ideal travel companion for short trips. Second, always add any bags you need during the booking process rather than at the airport, where fees can be two to three times higher. Third, check in online 24 hours before your flight to receive your boarding pass electronically and avoid any airport kiosk fees.

Fourth, purchase a seat selection if you are traveling with a companion and want to sit together, as Spirit's open-seating assignment process may separate unpurchased seat selections. Fifth, bring your own snacks and an empty water bottle to refill after security, as onboard food and beverage purchases add up quickly. Finally, compare the all-in total cost of a Spirit fare — including your expected add-ons — against the total cost of a comparable legacy carrier fare. In many markets, Spirit's total cost with one bag and seat selection still undercuts competitors by a meaningful margin, making it the smart choice for cost-conscious travelers.
