How do I check in for my Allegiant flight?

Checking in for an Allegiant flight is a straightforward process that can be done online or at the airport. For online check-in, travelers can visit the Allegiant Air website or use the mobile app. Online check-in typically opens twenty-four hours prior to the scheduled departure and closes one hour before the flight. To check in, passengers will need their confirmation number and last name, which allows them to access their flight details. During this process, travelers can select seats and potentially pay for any additional services, such as checked baggage. If travelers prefer to check in at the airport, Allegiant advises arriving at least two hours before the scheduled departure. Airport check-in requires travelers to go to the Allegiant ticketing counter, where they can present identification and receive their boarding passes. It is important to keep in mind that travelers should always verify their flight status and any specific check-in requirements by visiting the Allegiant website for the most current information. The website also provides guidance on any additional procedures that may be in place, especially in relation to travel requirements.
