jetBlue has strict guidelines for what you can and cannot bring on the plane with you. This includes carry-on bag dimensions, personal items, liquids, and other prohibited items.

In this article, we’ll explain everything you need to know about jetBlue’s carry-on policy so you can board your flight without any issues.

jetBlue Carry-On Rules

jetBlue allows one carry-on bag and one personal item onboard at no charge.  The personal item must fit under the seat in front of you, and the carry-on bag must be stowed in the overhead bin.

jetblue Carry-On Size and Personal item size

jetBlue Carry-On Dimensions

jetBlue’s size requirements for a carry-on are 22 x 14 x 9 inches (58 x 35 x 23 cm). Personal items must not exceed 17 x 13 x 8 inches (43 x 33 x 20 cm).

If you aren’t sure what size your carry-on is, jetBlue has carry on bag sizers located at their ticketing counters and departure gates.

If your bag is too big, you will have to check it (and possibly pay a fee), so it’s better always to know your bag size and the airline size restrictions in advance.

Carry-On Weight Limit

jetBlue doesn’t impose weight restrictions on a carry-on bag. However, when checking a bag, the weight limit is 50 pounds per bag.

jetBlue Carry-On Guarantee

jetBlue offers a carry-on guarantee that is unique to them. I am not aware of any other airline that will guarantee a carry-on. Here are the terms:

Customers traveling on domestic flights within the U.S. with a Blue, Blue Extra, and Mint fare, or who purchase an Even More Space seat (on all legs, if connecting), are guaranteed that their carry-on bag will make it on board as long as it meets all the requirements.

If your bag doesn’t make it on board, you’ll receive a $25 JetBlue travel credit.

For all other routes, overhead bin space is first-come, first-served, and based on availability. If you’re in a later boarding group, you may be required to gate-check your carry-on bag.

Recommended Carry-On Baggage For jetBlue

If you are looking for a great carry-on bag when flying jetBlue, I recommend the Travelpro Maxlite 5 Expandable Spinner. I have used this carry-on for years. It’s durable, reasonably priced, and holds everything I need for shorter trips.

Our Pick
Travelpro Maxlite 5 21" Carry-On Expandable Spinner
Travelpro Maxlite 5 21" Carry-On Expandable Spinner

This carry-on bag has been sizer bin tested to accommodate overhead bin space on most major US airlines.

Case Dimensions:

  • H: 21 in. W: 14 in. D: 9 in.

Note: If fully expanded it may not meet overhead bin size limits, so be careful to not overpack.

jetBlue Personal Item Size

Personal items include a purse, briefcase, laptop, backpack, shopping bag, or a similar-sized item.

Personal items must not exceed 17″ L (43.2 cm) x 13″ W (33 cm) x 8″ H (20.32 cm).

The following items may be brought onboard without counting toward your carry-on limit.

  • Duty-Free items (a reasonable and limited amount)
  • One diaper bag (for customers traveling with a lap infant) as a carry-on item
  • Special items (coat, umbrella, infant car seat, etc.)
  • Assistive devices (wheelchairs, canes, walkers, etc.)

jetBlue Carry-on Liquids Policy

The rules for carry-on liquids are set by the TSA (Transportation Security Administration), not by the airline.  jetBlue doesn’t have its own specific Liquids Policy, they just enforce the rules and policies of the TSA.

Each passenger may carry liquids, gels, and aerosols in travel-size containers that are 3.4 ounces or 100 milliliters. Each passenger is limited to one quart-size bag of liquids, gels, and aerosols. Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, shampoo, conditioner, perfume, mouthwash, deodorant, and lotion.

Exceptions to this rule are certain medications and baby food/child nourishment.

jetBlue Carry-On Pet Policy

jetBlue Airlines may not charge for your carry-on bag, but they will charge for your carry-on pet.

If you’re going to bring a pet on board with you, it must be able to fit in a small, ventilated pet carrier that fits under the seat in front of you.  Your pet carrier will count as a carry-on bag and cannot exceed 17″L x 12.5″ W x 8.5″H, and the combined weight of your pet and the carrier must not exceed 20 pounds.

Here are a couple of other things to be aware of:

  • Only one pet per customer is allowed.
  • A limited number of pets are allowed on each flight, so it’s best to book early.
  • Carry-On pets are not allowed in Mint.
  • Pets are not accepted on interline/code share bookings, regardless of booking source.
  • Pets are not permitted on flights going to Jamaica, Barbados, St Lucia, the Cayman Islands, or Trinidad & Tobago.
  • TrueBlue members earn 300 extra points per segment for adding a pet to their booking.

jetBlue Carry-On Pet Fees

Here is a chart showing the pet fees jetBlue charges each way.   Double them for a round-trip flight.

To/From DestinationPet Fee Each Way
Any jetBlue Airlines Flight $125.00

Recommended Pet Carrier for jetBlue

If you do plan on bringing your pet with you, make sure you follow TSA’s pet policy and have an approved Pet Carrier that conforms to jetBlue’s pet policy.

Our Pick
Sherpa Deluxe Travel Bag Pet Carrier, Airline Approved
Sherpa Deluxe Travel Bag Pet Carrier, Airline Approved

Features mesh panels so your pet can breathe easily, a non-slip shoulder strap, locking zippers, and a rear storage pocket for treats and other goodies.

Approved for use on most major airlines and the small and medium sizes are included in Sherpa's exclusive Guaranteed on Board program.

Prohibited and Restricted Items

Prohibited items are weapons, explosives, and incendiaries. This includes items that are seemingly harmless but may be used as weapons (dual-use items). You may not bring these items to security checkpoints without authorization.

Here is a list of items that are strictly prohibited on jetBlue flights:

  • Aerosol products (such as cooking spray or anti-static spray)
  • Household Cleaners such as bleach, drain cleaners, or pesticides 
  • Car Batteries
  • Fireworks or explosives
  • Ammunition, gunpowder, black powder, mace, and pepper spray
  • Torch or blue flame lighters and all lighter refills
  • Fuel (gasoline or sterno cans)
  • Meals Ready to Eat (MREs)
  • Pocket knife
  • Paints, stains, or lubricant 
  • “Strike-anywhere” matches 
  • Safety razors and straight razor blades
  • Hoverboards, balance gliders, self-balancing boards, or motorized riding suitcases that use lithium or lithium-ion batteries 
  • Items with refrigerants including refrigerators, air conditioners, freezers, or dehumidifiers

It’s important to note that this is not an exhaustive list and that the TSA’s rules and regulations are subject to change. Additional prohibited or restricted goods and materials can be found in the following resources:

  • IATA Dangerous Goods Regulations
  • TSA Permitted and Prohibited Items
  • FAA Packsafe List

jetBlue Carry-On Fees

jetBlue does not charge a fee for carry-on baggage that meets their size requirements.  If your bag is too large and does not meet jetBlue’s carry-on restrictions, you may be charged a fee to gate check it.

      Typically, the rules do not change with age. With the exception of special medications and formula for infants.

      Did you book a blue basic fare? That might be the issue. A carry-on bag is not allowed with a blue basic fare, just a personal item.
