Allegiant Air Baggage Policy

Allegiant Air allows a carry-on bag up to 22 x 14 x 9" (56 x 36 x 23 cm), including handles and wheels. There is no published weight limit, but you must be able to lift your bag into the overhead bin unassisted.

The personal item on Allegiant Air must fit within 16 x 15 x 7" (41 x 38 x 18 cm) and slide fully under the seat in front of you. Included free. Must fit under the seat in front of you.

The first checked bag on Allegiant Air costs $50 on most domestic economy fares, and the second bag costs $50. Allegiant is a ULCC with fully à la carte pricing. Checked bag fees range from $15 to $70 each way depending on route, season, and when you pay. At the airport, fees jump to $75 each way per bag. Allegiant prices carry-on and checked bags separately per route; use the bag price calculator at allegiantair.com for your specific flight. Max bag 40 lb / 80 linear inches on most routes.

Bags weighing 51 to 70 lb incur an overweight fee of $50. Bags 71 to 100 lb are charged $75. Oversize bags between 63 and 80 linear inches are $75. Fees are charged in addition to the standard checked bag fee.

No. Allegiant Air Base Fare passengers are limited to one personal item that fits under the seat. A full-size carry-on either is not allowed or costs an extra fee.

Four common ways: (1) pack in a carry-on and personal item only (confirm your bag fits the Allegiant Air carry-on size of 22 x 14 x 9"); (2) hold a Allegiant Air co-branded credit card, which typically waives the first checked bag fee for the cardholder and companions on the same reservation; (3) reach elite status in the airline's frequent flyer program, where mid-tier and above usually waive one or two bags per direction; (4) book a higher fare class (Premium Economy, Business, First) where checked bags are included.

Allegiant Air currently has a high gate-check risk based on our review of boarding policies and traveler reports. Plan on your carry-on being sized at the gate and be prepared to pay if it does not fit the sizer.
