Frequently asked questions
What is the Viva Aerobus personal item size limit?
Viva Aerobus allows a personal item up to 18 x 14 x 8" (45 x 35 x 20 cm). Must fit under the seat. The only free cabin item on Zero fare.
Does a backpack count as a personal item on Viva Aerobus?
Yes. A standard daypack or laptop backpack (about 18 x 13 x 8 inches) fits within the Viva Aerobus 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 Viva Aerobus weigh personal items?
Personal item weight is not published by Viva Aerobus 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 Viva Aerobus?
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. 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 Viva Aerobus Basic Economy?
Often no. Viva Aerobus 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.
