Allegiant allows passengers to print their boarding passes online. Twenty-four hours prior to departure, passengers can visit AllegiantAir.com, select Check-in Online, follow the instructions to verify seating assignments and bag reservations, and then print out the boarding passes.
Passengers can also download and use the free Allegiant2Go App to obtain paperless boarding passes on their mobile phones. Allegiant recommends that passengers obtain their printed or paperless boarding passes prior to arriving at the airport.
As of April 2015, there is a $5 fee for passengers who have Allegiant agents print boarding passes for them upon arrival at the airport. Allegiant often requires passengers with pets or special needs to check in at the airport ticket counter. In that case, the $5 fee does not apply.
