Frequently asked questions

What is the British Airways personal item size limit?

British Airways allows a personal item up to 16 x 12 x 6" (40 x 30 x 15 cm). Laptop bag, handbag, or small backpack. Must fit under the seat in front of you.

Does a backpack count as a personal item on British Airways?

Not always. A typical 18 x 13 x 8 inch backpack is larger than the British Airways published personal item limit of 16 x 12 x 6", so it may be treated as a carry-on. Slimmer laptop backpacks often still fit. Measure yours before flying.

Does British Airways weigh personal items?

Personal item weight is not published by British Airways 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 British Airways?

If your bag exceeds 16 x 12 x 6", 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 British Airways Basic Economy?

Often no. British Airways 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.
