If your personal item is larger than 18 x 14 x 8 inches, spirit airline personal item size, will classify it as a carry-on or checked bag, resulting in additional charges. At the airport, Spirit Airlines staff may measure your bag at the gate, and if it exceeds the limit, you will be required to pay a carry-on fee, which is significantly higher when paid at the gate. To avoid this, always measure your bag before heading to the airport and ensure it fits under the seat. If you need more space, pre-purchasing a carry-on or checked bag online can save money compared to last-minute airport fees.
