Frequently asked questions
What is the Frontier Airlines personal item size limit?
Frontier Airlines allows a personal item up to 14 x 18 x 8" (35 x 46 x 20 cm). Included free. Must fit fully inside the gate sizer or you will be charged as a carry-on.
Does a backpack count as a personal item on Frontier Airlines?
Yes. A standard daypack or laptop backpack (about 18 x 13 x 8 inches) fits within the Frontier Airlines personal item limit of 14 x 18 x 8". Larger travel or hiking backpacks may exceed that limit and will be treated as a carry-on.
Does Frontier Airlines weigh personal items?
Personal item weight is not published by Frontier 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 Frontier Airlines?
If your bag exceeds 14 x 18 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 $59 on Frontier 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 Frontier Airlines Basic Economy?
Often no. Frontier 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.
