Personal Item Dimensions:
Both Frontier and Spirit Airlines permit one personal item per passenger, which must fit under the seat. For Frontier, the personal item dimensions must not exceed 18 x 14 x 8 inches (45 x 35 x 20 cm), and Spirit Airlines has an identical restriction of 18 x 14 x 8 inches (45 x 35 x 20 cm) for personal items, including bags, backpacks, and purses.
