Passengers are permitted to bring one complimentary personal item on Frontier Airlines, but it must meet stringent size requirements. A personal object can have no more than 14 inches by 18 inches by 8 inches (including handles, wheels, and straps). A laptop bag, briefcase, pocketbook, or small backpack can be included; it only needs to fit beneath the seat in front of you. Larger items will be charged extra as carry-ons, which are subject to these restrictions.
