Florida-based Spirit Airlines (NK) flies non-stop to more than 55 destinations in the United States, Caribbean, Central America and South America. The carrier, which is not part of a major airline alliance, operates a fleet configured entirely with Economy Class seating. For an additional fee, passengers can reserve Big Front Seats, which are wider seats with more legroom located at the front of the plane. Travelers can also pay additional fees for checked baggage and onboard drinks and snacks. Spirit Airlines has two operating bases: Detroit Metropolitan Wayne County Airport (DTW) and Fort Lauderdale – Hollywood International Airport (FLL).
