Spirit Airlines is an ultra-low-cost carrier, which means that it keeps ticket rates low by charging extra for services such as baggage. Unlike most airlines, Spirit does not include free carry-on or checked luggage in the base cost (save for one personal item).

Personal Item Allowance Every passenger is allowed to carry one free personal item on board. It could be a handbag, tiny backpack, or laptop bag.

Dimensions: 18 x 14 x 8 inches (45 x 35 x 20 cm), including handles and wheels. Examples: laptop bag, tiny backpack, and handbag.
