The personal item is checked at boarding

Frontier checks the personal item’s size as you board, and a bag over 18 x 14 x 8 inches costs an extra charge there. Frontier names purses, totes, computer bags, briefcases and kids’ backpacks as personal items. Coats, canes, crutches, portable oxygen concentrators, respiratory devices and other assistive devices are exempt from carry-on charges.
