Is Allegiant Air Safe? Allegiant Air is generally considered a safe airline. It operates under strict regulations set by the Federal Aviation Administration (FAA), like all US-based carriers. While it has faced scrutiny in the past for maintenance and operational issues, the airline has taken steps to improve safety standards. Allegiant primarily uses newer Airbus A320 series aircraft, replacing older planes over time. It's important to note that flying with any major US airline, including Allegiant, is statistically very safe. Passengers should always stay informed, but overall, Allegiant remains a viable and secure option for budget-conscious travelers seeking domestic flights.
