Allegiant Air Launches 39 New Routes From Florida: See All Flights Now [Full List]

Allegiant Air will add 39 new and returning routes in Florida for September 2026, based on a year-over-year comparison of its schedules against September 2025. While the ULCC’s flights regularly touch the Sunshine State—58% of its point-to-point flying in September—the change extends its network across 12 Florida airports. The net result is a gain of 21 links year-over-year: 39 routes added against 18 Florida airport pairs removed. Nearly half of the additions come from Orlando Sanford International (SFB) and Fort Lauderdale-Hollywood International (FLL), with SFB to Key West the only intrastate link at 254 nautical miles each way (470 km).
