What is a carry-on size limit?

A carry-on size limit refers to the maximum dimensions and weight allowed for a piece of luggage that can be brought onboard an airplane and stored in the overhead bin or under the seat in front of you.

Why do airlines have carry-on size limits?

Airlines have carry-on size limits to ensure that there is enough space in the overhead bins for all passengers’ luggage, as well as to comply with safety regulations regarding weight limits and storage space.

How do I measure my carry-on luggage to ensure it meets the size limit?

To measure your carry-on luggage, use a tape measure to determine the length, width, and height of the bag. Make sure to include any wheels or handles in your measurements.

Can I bring a carry-on bag and a personal item onboard?

Yes, most airlines allow passengers to bring one carry-on bag and one personal item, such as a purse or laptop bag, onboard. However, make sure to check with your specific airline for their policy.

What happens if my carry-on luggage exceeds the size limit?

If your carry-on luggage exceeds the size limit, you may be required to check it in at the gate, which could result in additional fees. It is always best to double-check the size restrictions before boarding.
