Does Jetblue allow carry-on?

You are allowed one carry-on item that must be placed in the overhead bin and not exceed external dimensions of 22in x 14in x 9in. You are allowed one checked bag 60 (157.48 cm) in overall dimensions (length + width + height) or 50 pounds (22.68 kg). The fee for the second bag is $45 and only available at the airport.



Whether JetBlue allows a free carry-on bag depends strictly on the type of fare you purchased. For most travelers in 2026, including those in Blue, Blue Plus, Blue Extra, and Mint classes, JetBlue allows one standard carry-on bag for the overhead bin and one personal item that fits under the seat, both free of charge. However, if you purchase a Blue Basic fare (their version of "Basic Economy"), you are not permitted a carry-on bag for the overhead bin; you are only allowed one personal item. If you bring a carry-on to the gate with a Blue Basic ticket, JetBlue will charge a significant fee (often $65 or more) to gate-check the bag to your final destination. There are exceptions for Mosaic members, travelers on transatlantic flights, and active military personnel, who are generally allowed a carry-on regardless of their fare type. JetBlue has also recently introduced a "Carry-On Guarantee" for many of its higher-tier fares, promising that if your bag is forced to be checked due to lack of space, you will receive a small travel credit as a gesture of goodwill.

Blue Basic fares include 1 personal item that fits under the seat in front of you, like a purse, daypack, laptop bag or pet carrier. Any additional or larger carry-on bags brought to the gate will incur a fee and need to be checked. The fee is $65 (if it would be your 1st or 2nd checked bag) or $180 (if it's your 3rd).

In general, your personal item should be smaller than your carry-on and under the specific airline's carry-on dimensions, allowing it to fit under the seat in front of you. In most cases, backpacks are considered personal items as long as they fit under the seat in front of you.

Most airlines allow passengers to bring on both a carry-on and a personal item like a backpack, laptop bag, purse, briefcase, shopping bag, etc. The general rule of thumb is that your personal item is smaller in dimension than your carry-on bag and it can fit underneath the seat in front of you.

Many airlines will allow you to bring a carry-on bag and personal item for free. However, some airlines may only allow a personal item that fits under your seat for free. Anything larger (e.g. a bag that's too big to fit under the seat but can fit into the overhead compartment) may require extra payment.

But it's not just about unbundling and charging customers more. A key driver in domestic checked baggage fees is tax arbitrage. Airlines want to get a portion of the transportation cost out from under the base airfare so that it is not subject to the government's 7.5% excise tax on tickets.

It's rare to find U.S. airlines with free checked baggage. Southwest Airlines is the only airline without any bag fees. For other airlines, you'll need to earn elite status or book your tickets with an airline credit card.

Usually, many airlines won't check every carry-on but will instead go for ones that look oversized. If your luggage does not fit in the sizer, you might have to pay a checked bag fee along with the gate checking fee and have your bag transferred to the airplane's cargo.
