Allegiant Air

Über uns Allegiant Air

Allegiant Air (IATA: G4, ICAO: AAY) is an US airline.

Allegiant Air is a unique ultra-low-cost US carrier that specialises in leisure travel from small and medium-sized US cities to vacation destinations like Las Vegas, Orlando, and Florida beach towns. Unlike most US carriers, Allegiant flies non-daily schedules — typically 2-4 flights per week on each route — keeping costs extremely low.

Did you know? Allegiant Air operates a non-hub point-to-point model serving leisure destinations with non-daily frequency from smaller US secondary airports — a strategy that avoids direct competition with major carriers at large hub airports.
