JAL (Japan Airlines) domestic baggage rules include several important details you should check before your trip, such as the 10 kg carry-on baggage limit and the latest rules for power banks.

Compared with many low-cost carriers (LCCs), JAL offers a more generous free checked baggage allowance. However, baggage size limits and prohibited item regulations are strictly enforced.

To avoid last-minute problems at the airport, it's best to familiarize yourself with JAL's baggage rules before your departure.

In this guide, we'll explain everything you need to know about JAL domestic baggage rules, including carry-on baggage, checked baggage, size restrictions, power bank regulations, and prohibited items, in a simple, easy-to-follow format for first-time travelers.

JAL Domestic Carry-on Baggage Rules: Size, Weight, and Item Limits

Carry-on Baggage Allowance

JAL domestic flights have specific rules regarding the size, weight, and number of bags you may bring into the cabin.

※ Wheels, handles, pockets, and other protruding parts are included when measuring baggage size.

※ If your itinerary includes a flight on an aircraft with fewer than 100 seats, the smaller aircraft's carry-on size limits will apply.

Although JAL's carry-on baggage allowance is generally more generous than that of most low-cost carriers (LCCs), baggage exceeding the permitted size or weight may need to be checked at the boarding gate before departure.

Important Carry-on Tips

• The combined weight of all carry-on baggage must not exceed 10 kg (22 lbs).
• Bags exceeding the permitted size may need to be checked.
• Portable batteries (power banks) cannot be placed in checked baggage and must be carried in the cabin.
• Your bag must be light enough for you to lift into the overhead compartment without assistance.
• If overhead bin space becomes limited, you may be asked to check your bag at the boarding gate.

Common Items with Carry-on Restrictions

Items Allowed with Restrictions

JAL Domestic Flights: Power Bank Rules

Most Important Rule

Power banks cannot be packed in checked baggage on JAL domestic flights.

Because lithium-ion batteries pose a fire risk, they must always be carried in your carry-on baggage.

Power Bank Carry-on Rules

• Only power banks rated at 160Wh or less are permitted.
• You may carry up to two power banks per passenger.
• They must always be carried in your carry-on baggage.
• Keep them with you during the flight rather than placing them in the overhead compartment.
• Charging the power bank itself during the flight is prohibited.
• Using a power bank to charge smartphones, tablets, or other devices during the flight is also prohibited.
• To help prevent short circuits, it is recommended that the battery terminals be protected.

Why Are the Rules So Strict?

In recent years, there have been multiple reports of lithium-ion batteries overheating or catching fire on board aircraft. As a result, airlines have strengthened their safety regulations for power banks.

To reduce the risk of onboard fires, power banks and the removable batteries used in smart luggage cannot be placed in checked baggage.

Always carry them in your carry-on baggage.

To avoid delays or problems at the airport, check your power bank's capacity and ensure it meets the airline's requirements before traveling.

Airport security inspections are often stricter during busy travel periods, such as the summer vacation season and major holiday periods.

Rules for Carrying Liquids on JAL Domestic Flights

• On JAL domestic flights, you may bring beverages such as water, tea, and juice on board.

• Cosmetics, perfume, and non-radioactive medications may be carried in containers of up to 0.5 L (0.5 kg) each, with a combined limit of 2 L (2 kg).

Medications & Baby Formula

Permitted Items

• Medications required for use during the flight may be carried on board.
• Passengers traveling with infants may bring baby formula and baby food.
• Medically necessary items, such as diabetes medication and CPAP equipment, are also permitted.
• Security officers may ask you to explain or verify these items during screening.
• If available, bringing a doctor's note or prescription may help speed up the security screening process.

JAL does not provide onboard refrigeration for medications or baby formula. If temperature control is required, bring an insulated cooler bag or another suitable storage solution.
