On Spirit Airlines in 2026, you can bring one personal item for free, but you cannot bring both a purse and a backpack unless one can fit entirely inside the other. Spirit's strict "one personal item" policy means that any bag you bring must fit within the dimensions of 18 x 14 x 8 inches (45 x 35 x 20 cm) and must be placed under the seat in front of you. If you show up at the gate with a separate purse and a backpack, the gate agent will likely require you to consolidate them or pay a significantly higher "Gate Bag" fee—which in 2026 can be as high as $99—to count the second item as a carry-on. To maximize your space without paying extra, many savvy 2026 travelers use a small "personal item-sized" backpack and tuck their thin crossbody purse or laptop sleeve inside it during the boarding process. Once you are in your seat, you can take the smaller items out. Note that items like umbrellas, cameras, and infant diaper bags typically do not count toward your limit, but a standard purse is definitely considered a distinct personal item.
