Can you bring pumped breast milk on a plane with JetBlue Airways when traveling with a baby?

Bringing pumped breast milk on a JetBlue flight

Yes — you can bring pumped breast milk on a JetBlue flight when traveling with a baby. JetBlue follows U.S. transportation security rules that allow passengers traveling with infants to carry breast milk, formula, and baby food in quantities greater than the usual 3.4 oz (100 ml) limit. Below are practical, real-world details and tips so your travel goes smoothly:

• Declare it at security: When you reach the TSA checkpoint, tell the officer you are carrying breast milk and present the containers separately for inspection. They will screen the milk by X-ray or other tests instead of enforcing the 3.4 oz restriction.
• Screening procedures: TSA may X-ray the containers or perform additional screening such as explosive trace detection or opening the container for visual inspection. Officers are trained to handle breast milk respectfully. If an X-ray is used, it is safe for breast milk; if a sample is needed for testing, officers will follow procedures to protect the milk as much as possible.
• Ice packs and coolers: You may bring ice packs, frozen gel packs, or dry ice to keep milk cold. If an ice pack is completely frozen at screening, it’s allowed without being counted as a liquid. If partially thawed, it may be treated as a liquid and subject to screening rules. Pack bottles in an insulated cooler bag with freezer packs or use a portable electric cooler if you need refrigeration in transit.
• Carry-on is best: Store pumped milk in your carry-on rather than checked baggage so you can monitor temperature and access it during the trip. JetBlue cabin crew generally cannot guarantee refrigeration on board, so plan to keep milk cold yourself.
• Quantity: There is no strict U.S. quantity limit for breast milk when traveling with an infant, but carry a reasonable amount for your trip. TSA allows “reasonable quantities” for infants and will screen them accordingly.
• Breast pump and batteries: You can bring a breast pump and spare batteries in carry-on baggage. If you have spare lithium batteries, they should be carried in the cabin and protected from short circuits (e.g., tape exposed terminals or keep in original packaging).
• Labeling and documentation: It’s helpful (but usually not required) to label containers with your name and the date. You don’t normally need a doctor’s note. For international travel, check destination entry rules for infant food or milk and any customs requirements.
• Onboard feeding: You are allowed to feed your baby breast milk on board. Flight attendants are generally helpful if you need a cup of warm water or space to store a small container temporarily, but don’t rely on the aircraft offering refrigeration.
• If traveling internationally: U.S. security rules allow breast milk through U.S. checkpoints, but rules at other countries’ airports may vary. Check the destination’s security and customs rules before travel and pack accordingly.
