JetBlue General Carry-on Policy

With the exception of Blue Basic fares booked on or after 2/25/21 for travel 7/20/21 or later, all fares also include 1 carry-on bag that fits in the overhead bin.

Including wheels and handles, carry-on bags must not exceed 22″ L (55.88 cm) x 14″ W (35.56 cm) x 9″ H (22.86 cm).

If you’re booking 2/25/21 or later for travel 7/20/21 or later and prefer to carry on your bags or stow something in the overhead bin, be sure to book a Blue, Blue Plus, Blue Extra or Mint fare.

Starting 7/20, on domestic flights within the U.S , passengers traveling on a Blue, Blue Extra and Mint fare or who purchase and Even More® Space seat holders are able to carry their carry-on on board, as long as it meets all the requirements.

For other destinations, overhead bin space is first-come, first-served, based on availability.

Passengers boarding late or last may be required to gate-check their carry-on bags.

Please note that carry-on bags must be stowed properly in the overhead cabin or under the seat in front of you, while your personal item must be placed under the seat in front of you.

If your carry-on bag does not fit in the overhead compartment, prepare to send your bag as a checked bag.

Since you won’t have access to your checked baggage, make sure that you take all your travel documents, medication and expensive items in your cabin baggage or personal item, which will be with you during your flight. You should also remember to label your checked baggage with your name and contact information in case something happens.


JetBlue Personal Item

According to JetBlue, All JetBlue Guests are allowed 1 personal item—like a purse, daypack, laptop bag or approved pet carrier—that fits under the seat in front of you and doesn’t exceed 17″ L (43.2 cm) x 13″ W (33 cm) x 8″ H (20.32 cm).

Additional small items

In addition to your carry-on bag and personal item you can bring additional items free of charge.

These items are not counted toward your main carry on bag.


JetBlue Carry-on Liquids Policy

All US airlines including JetBlue follow the TSA liquid rules.

So if you are planning to bring liquids on your flight you will be resumed to follow the TSA 3-1-1 liquid rules.

No more than 3.4 oz / 100 ml for each container packed in a single quart sized bag, you will be repaired to remove your liquids form your carry on bag and placed in a separated bin for further screening.
