Permitted carry-on items

Information on the 3-1-1 Directive

3-1-1 for carry-on bags = 3.4 oz/100 ml bottle or less; one quart-sized, clear, plastic, zip-top bag; one bag per customer placed in screening bin. One quart-sized bag per person limits the total liquid volume each traveler can bring. The 3.4 oz/100 ml container size requirement is a security measure.

Customers are prohibited from taking liquids, gels, and/or aerosols past the airport security screening checkpoint EXCEPT:

  • One clear transparent, resealable one-quart (one-liter) sized plastic bag containing liquids, gels, and aerosols in travel size containers (3.4 oz./100 ml capacity) or less per container
  • The contents of the plastic bag must fit comfortably and the plastic bag must be completely sealed, be taken out of the carry-on bag and placed in a security bin
  •  Alcohol Guidelines

Please note: liquids, gels, and aerosols include beverages, shampoo, suntan lotion, creams, toothpaste, hair gel, hair spray, and other items of similar consistency.

Liquid Exemptions (exempt items more than 3.4 ounces/100 ml)

Customers may have the following items, but must declare them to TSA at the security checkpoint if the items are not contained in a clear transparent resealable one-quart (one-liter) sized plastic bag and/or the size of the containers exceed travel size (3.4 oz/100 ml):

  • Baby formula or milk (to include breast milk)
  • Baby food and/or juice in containers if a baby or small child is traveling
  • Medications (liquid, gel, and aerosol)
  • Liquids (to include juice) or gels for diabetic or other medical needs
  • Items used to augment the body for medical or cosmetic reasons such as mastectomy products, prosthetic breasts, bras or shells containing gels, saline solution, or other liquids
  • Gels or frozen liquids needed to cool disability or medically-related items used by persons with disabilities or medical conditions

Customers may be subjected to a secondary screening if they enter the screening checkpoint with liquids, gels, and aerosols on their person or in their carry-on bag.

Traveling with Formula, Breast Milk, or Juice

When carrying formula, breast milk, or juice through the checkpoint, customers will be inspected; however, the customer or their baby or toddler will not be asked to test or taste breast milk, formula, or juice. The TSA Security Officers may test liquid exemptions (exempt items more than 3.4 ounces/100 ml) for explosives.

When traveling with a child, in the absence of suspicious activity or items, greater than 3.4 ounces of baby formula, breast milk, or juice are permitted through the security checkpoint in reasonable quantities for the duration of the customer's itinerary, if the customer performs the following:

  1. Separate these items from the liquids, gels, and aerosols in your quart-size and zip-top bag.
  2. Declare you have the items to one of our Security Officers at the security checkpoint.
  3. Present these items for additional inspection once reaching the X-ray. These items are subject to additional screening.

Customers are encouraged to travel with only as much formula or juice in their carry-on needed to reach your destination.

Duty-free Items

Customers are permitted to take onboard the aircraft duty-free items, liquids, gels, and/or aerosols purchased inside the sterile area onboard the aircraft once they have gone through the security checkpoint.

Please note: On international flights, including Puerto Rico and U.S. Virgin Islands, customers with duty-free purchases are allowed to carry a reasonable amount onboard the aircraft. Limitations vary based on the customer’s final destination. 

Please allow additional time for check in at the airport to allow sufficient time to go through the security checkpoint.

Customers may send questions directly to TSA at the following email address:

      • Two spare batteries are permitted per Customer and the battery does not exceed 160 watt hours.

Medication Permitted in Carry-on Bags

All medications in any form or type (for instance, pills, injectables, or homeopathic) and associated supplies (syringes, sharps disposal container, pre-loaded syringes, jet injectors, pens, infusers, etc.) are allowed in carry-on bags once they've been pre-screened at the security checkpoint. Atropens, an auto-injection system that can help treat many emergency conditions (low heart rate, breathing problems, and excess saliva related to insecticide, nerve gas or mushroom poisoning) are also allowed.

Medications should be labeled so they are identifiable.

All vital medicines, including insulin, pills and/or other prescribed medication must be hand-carried. We recommend all medication is carried in the original prescription container when possible.

JetBlue cannot assume liability for any medical complications and/or expenses incurred as a result of any medication not available for use while en route.

JetBlue will not carry persons who require medical oxygen onboard. Due to safety reasons, we do not permit any type of oxygen to be brought on the aircraft nor do we supply medical oxygen onboard.

Refrigerators are not available for storage; however, you may carry on a small insulated cooler that meets the carry-on requirements.

Assistive and special devices as carry-on or checked bags

There's no limit to the number of assistive devices you can bring onboard the aircraft. Assistive devices will not be considered as part of the carry-on or checked baggage limit; however, they are subject to carry-on size and weight restrictions.

Assistive devices include (but are not limited to):

  • Car seats
  • Crutches
  • Canes
  • Child carriers/backpack carriers 
  • Walkers
  • Braces/prosthesis
  • Wheelchair
  • Wheelchair batteries
  • Strollers
  • Breast pump
  • POC and CPAP machines

Most assistive devices will fit in the overhead bins. If not, we can gate-check it, and it will be one of the first items brought to the jetbridge. You may also request to pick it up at baggage claim.

JetBlue will accept assistive devices with batteries as a checked bag as well as onboard the cabin. Assistive devices with batteries include respirators, CPAP machines, portable oxygen concentrators (POCs) and ventilators. JetBlue will allow qualified individuals with a disability who are using personal respirators/ventilators to bring their equipment, including non-spillable batteries, onboard the aircraft.

The FAA provides guidance for safely bringing your assistive devices. Visit them here:

*Note: Batteries used for assistive devices are required to be non-spillable and the outer packaging must be plainly and durably marked “NONSPILLABLE” or “NON-SPILLABLE BATTERY,” or completely enclosed in a case. If a battery is not labeled "non-spillable" or completely enclosed in a case, crewmembers must treat the battery as a spillable battery. Crewmembers will apply the acceptance procedures for spillable batteries as required under the FAA safety regulations.

Medical Devices

If powered by a nonspillable battery, the following items may be used during the flight for health or medical reasons.

  • Hearing aids
  • Inhalers
  • Insulin pumps
  • Pacemakers
  • Breast pump (must be battery powered in order to be used during flight.)
  • Approved Portable Oxygen Concentrators (POC) (click here for requirements)

Continuous Positive Airway Pressure machines (CPAP)

Portable electronic personal ventilators, respirators, and continuous positive airway pressure (CPAP) and BiPAP machines may be carried and used on board JetBlue, in accordance with specific FAA guidelines.

Please note some of our aircraft have in-seat electrical power, but it is not available for ventilators, respirators, BiPAP or CPAP machines.  

Ventilators, respirators and CPAP machines are considered assistive devices. They must be stowed and used in the cabin consistent with applicable TSA, FAA and other regulations governing carry-on bags.

Bringing Batteries for Electronic Devices

Due to the possibility of a fire, all batteries for electronic devices should be packed in the original retail package and wrapped in insulating tape to prevent loose batteries from coming into contact with metal objects.

Please note: Lithium batteries should be packed in carry-on bags, not checked bags, to protect the battery from getting crushed or punctured during the flight.

Orthopedic Positioning Devices (OPD)

OPDs are assistive devices used by customers with disabilities in order to support themselves in such a way that the aircraft's seatbelt can be used as an effective and primary method of restraint. The use of this type of OPD is appropriate and permitted on aircraft and is not prohibited by current regulations.

OPDs are devices or supportive braces that are designed and used to help support and position a person who has:

    • Significant postural asymmetries of the pelvis, trunk, and or hips that lack flexibility
    • Significant hyper or hypotonia, plasticity, or mixed athetoid dysfunctions
    • Absent or impaired sensation in an area of contact with a seating surface
    • Past history of, or current pressure ulcer, on an area of contact with a seating surface

OPD Usage Requirements:

  • The OPD must be equipped with internal restraints to position a person in the device to provide that person security and support.
  • The OPD must not attach to the seat, but must be properly positioned in order to use the existing aircraft seatbelt as the primary restraint device.
  • The aircraft seatbelt must secure around the person using the OPD and provide the primary method of restraint.
  • An OPD may be used in any seat except an exit row, provided it does not block any customer's exit from the aircraft.
  • The OPD is not intended to be identified, sold or used as a child restraint system.

There must be a medical need for the customer to use the OPD. This can come from observation of the customer or credible verbal assurance from them or their attendant.

Please note: we do not have OPDs available at the airport.

Portable Oxygen Concentrator (POC)

A Portable Oxygen Concentrator (POC) is a machine that takes normal room air and, using a series of sieves, filters, and a compressor, removes nitrogen from the air, increasing the oxygen content of the resulting air to up to 96%. JetBlue will allow individuals the use of certain POCs during flight.

Note: A POC is not to be confused with a compressed oxygen tank which Customers are strictly prohibited from carrying on any JetBlue aircraft.

Customers using Portable Oxygen Concentrators must have a sufficient number of fully charged batteries plus 50% extra battery time for the flight to cover any unforeseen delays. 

Customers that need additional oxygen while traveling must provide their own POC in order to travel. Please see additional clarifications here regarding POC travel.

Carry-on Bags for Travelers with Disabilities or Medical Conditions

You're not limited in the amount or volume of the items below that you may bring in your carry-on bag(s). However, if the medically-necessary items exceed 3.4 ounces or are not contained in a one-quart sized, zip-top plastic bag, you MUST declare it at the security checkpoint for further inspection.

The following items are permitted in your carry-on bag:

  • All prescription and over-the-counter medications (liquids, gels, and aerosols) including KY jelly, eye drops, and saline solution for medical purposes
  • Liquids including water, juice, or liquid nutrition or gels for customers with a disability or medical condition
