Booking out of FLL is usually the strongest fare play: Spirit Airlines concentrates 42 of its routess from Fort Lauderdale, and higher route density at a hub means more head-to-head competition — both from other Spirit Airlines departures and from rival carriers serving overlapping city pairs.

All route, hub, destination and country figures are computed directly from the OpenFlights public-domain routes dataset(openflights.org/data.php)— specifically the directCarriers JSON field on every FlightRoute row, where each airline code (e.g. NK) is parsed from the OpenFlightsroutes.dat airline identifier column. Carrier names come from the companion OpenFlights airlines.dat dataset. No prices or fare estimates appear on this page — those values fluctuate continuously across 100+ booking sites and are fetched live via Kayak at search time.
