Frequently asked questions

What is the Spirit Airlines personal item size limit?

Spirit Airlines allows a personal item up to 18 x 14 x 8" (46 x 35 x 20 cm). Included free with every fare. Must fit in the sizer at the gate or you will be charged.

Does a backpack count as a personal item on Spirit Airlines?

Yes. A standard daypack or laptop backpack (about 18 x 13 x 8 inches) fits within the Spirit Airlines personal item limit of 18 x 14 x 8". Larger travel or hiking backpacks may exceed that limit and will be treated as a carry-on.

Does Spirit Airlines weigh personal items?

Personal item weight is not published by Spirit Airlines and is rarely enforced at the gate for US domestic flights. On international routes, especially with codeshare partners, agents may weigh bags, so keep your personal item reasonable in weight.

What if my personal item is too big for Spirit Airlines?

If your bag exceeds 18 x 14 x 8", a gate agent can ask you to place it in the sizer. If it does not fit, you may need to pay a carry-on or checked bag fee, starting around $65 on Spirit Airlines. On Basic Economy fares, an oversized personal item is the most common cause of surprise fees.

Can I bring a personal item plus a carry-on on Spirit Airlines Basic Economy?

Often no. Spirit Airlines restricts Basic Economy passengers to a personal item only on many routes, with full-size carry-ons either banned or charged as a paid add-on. Read the fare rules at booking before you pack.
