Can you bring breast milk on a plane with Japan Airlines when traveling with a baby?

 

Bringing breast milk on Japan Airlines

 

Yes — you may bring breast milk, expressed milk, infant formula and baby food on board with Japan Airlines. These items are allowed in carry-on even if they exceed the usual 100 ml liquid limit, but you should follow security screening rules and airline guidance.

• Declare the items at security (airport security officers must screen them). Be ready to present the milk separately for inspection.
• Bring a reasonable quantity for the duration of your trip — typically what you need for the flight plus any reasonable delays.
• Containers and labeling: Use clear, sealed bottles or bags and label them if possible. Keep milk accessible (not packed deep in checked baggage).
• Ice packs and frozen milk: Solidly frozen milk or frozen ice packs are generally allowed. Partially thawed liquids may be screened further.
• Screening may require opening: Security may need to test or open containers; they should handle items carefully but plan for extra time.
• Onboard handling: Flight attendants can assist with warming or storing small amounts when staffing and equipment allow, but refrigeration is not guaranteed — bring appropriate insulated carriers.
• International differences: Airport security rules vary by country. Always confirm rules for departure and transit airports and with Japan Airlines if you have concerns about quantities or special needs.

If you want, I can help draft a short note to show security or check specifics for your departure airport and route.
