Frequently asked questions

What is the Cathay Pacific personal item size limit?

Cathay Pacific does not publish strict personal item dimensions. Your bag must fit fully under the seat in front of you, generally around 18 x 14 x 8 inches. A handbag, slim laptop bag, or small backpack is allowed in addition.

Does a backpack count as a personal item on Cathay Pacific?

Yes. Cathay Pacific does not publish strict dimensions, so a standard backpack that slides fully under the seat in front of you counts as a personal item. Overstuffed or bulky travel backpacks may be asked to go in the overhead bin.

Does Cathay Pacific weigh personal items?

Personal item weight is not published by Cathay Pacific 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 Cathay Pacific?

If your bag does not fit fully under the seat, the flight attendant may ask you to move it to the overhead bin or gate-check it. That can trigger a carry-on or checked bag fee on Basic Economy fares where only a personal item is included.
