Yes, passengers are allowed to bring a carry-on bag on Allegiant flights. However, there are some restrictions and fees associated with it. Each passenger is permitted to bring one personal item on board for free, such as a purse, laptop, or briefcase. If you wish to bring a larger carry-on bag, like a roller bag or duffel, there is a fee for this service. The cost depends on whether you choose to add it during booking, online check-in, or at the airport. It is recommended to add your carry-on bag during the booking process to secure the lowest fee. Allegiant's carry-on bag dimensions must not exceed 9 x 14 x 22 inches, and it should fit comfortably in the overhead storage bin or under the seat in front of you.
