Spirit Airlines can lift the spirits of people seeking sunshine. The ultra low-fare carrier (ULCC) makes connections between major US cities and popular vacation spots in South Florida, the Caribbean, and Latin America, serving more than 40 destinations. It operates an all Airbus fleet of about 30 single-aisle aircraft, including A319s, A320s, and A321s. Spirit capitalizes on an ancillary service model, charging separately for baggage, advance seat selection, and other travel-related upgrades. In addition to scheduled service, the company partners with third-party vendors to offer a slate of vacation packages via its website. In 2011 Spirit Airlines sought public investors, planning to land up to $300 million.
