Passengers are allowed one personal item, such as a backpack or laptop case, at no cost. Passengers may also bring aboard one carry-on bag, such as a small suitcase, for $10 to $75. Passengers may also check bags for $14.99 to $35 per bag; additional charges will apply for large or overweight bags. To receive the lowest possible bag fees, passengers must pay the fees in advance.

There are regular seats and giant seats available on most Allegaint aircraft. Giant seats are more common for longer flights. The giant seats are 25 inches across instead of the regular seats, which measure 17.5 inches. In addition to this, they offer 34 inches of space between seat rows, and regular seats are spaced 30 inches apart. This does not mean there is 30 or 34 inches of leg room. This is the measurement of the front side of the seat to the back of the seat in front of that one. Passengers who are wider than the seat’s width measurement will need to purchase an additional spot if they cannot use the seat belt with an extender or if they cannot raise and lower the armrests due to their girth.

Seats are assigned based on check-in time, but passengers can select a seat when they purchase their tickets by paying an additional fee.

After a ticket has been purchased, the buyer has up to 24 hours to cancel it and receive a refund. Changes can be made for a fee, but customers must do this within one week of the departure date. Fees depend on the type of change made, but customers can visit http://www2.allegiantair.com/terms-and-conditions for full details. People who book their flights with a debit card will also receive a discount.

Children two years of age or younger who will be sitting on an adult’s lap may fly free. If a child is over the age of two, an additional seat must be purchased.
