What should JetBlue carry-on dimensions be?

JetBlue allows one carry-on bag with maximum dimensions of 22 x 14 x 9 inches (including wheels and handles). This size ensures the bag fits in the overhead bin. Additionally, passengers may bring one personal item, such as a purse or laptop bag, that fits under the seat.
 
For most JetBlue fares, passengers can bring a carry-on bag up to 22 x 14 x 9 inches and a personal item measuring 17 x 13 x 8 inches. However, Blue Basic fares only permit a personal item; carry-on bags are not included unless purchased separately.
 
JetBlue does not impose a weight limit on carry-on bags, but passengers must be able to lift their bag into the overhead bin unassisted. Ensure your carry-on does not exceed 22 x 14 x 9 inches to comply with size regulations.
 
Your personal item should fit under the seat in front of you and not exceed 17 x 13 x 8 inches. Common personal items include backpacks, briefcases, or handbags. This is in addition to the standard carry-on allowance.
 
To ensure your carry-on fits in the overhead compartment, adhere to the 22 x 14 x 9 inches size limit. Bags exceeding these dimensions may need to be checked at the gate, potentially incurring additional fees
 
JetBlue permits one carry-on bag (max 22 x 14 x 9 inches) and one personal item (max 17 x 13 x 8 inches) per passenger. Note that Blue Basic fares exclude the carry-on bag unless added for a fee. Always check your fare details before packing.

JetBlue’s carry-on size limit is 22 x 14 x 9 inches, including wheels and handles, and I only truly memorized that after a near-miss at the gate. On a flight from Boston to Orlando, I packed a soft-sided bag that looked fine but was stuffed a little too much. At boarding, the agent had me slide it into the sizer, and thankfully it fit—barely.

Since then, I always measure at home and leave a bit of room so the bag isn’t bulging. JetBlue is usually reasonable, but on full flights they do enforce the size, especially if overhead space is tight. If your bag is bigger, you’ll need to check it, which can slow things down.

I’ve had to change flights once due to weather, and having a compliant carry-on made rebooking and reboarding much easier. Knowing the dimensions ahead of time really saves stress.
