How to pack carry-on items

  • Store liquid in containers with capacities not greater than 100 ml (g), and place the containers so that they fit comfortably in a transparent re-sealable plastic bag with a capacity of not more than 1 liter*.
    * Even if a container measures less than 100 ml, it cannot be brought on board if it is not placed in the plastic bag.
  • The recommended dimensions for the plastic bags are within 20 cm wide x 20 cm high. Expandable bags cannot be used as their capacities will exceed 1 liter.

    Passengers are responsible for purchasing their own the plastic bags. Bags can be purchased at convenience stores, home centers, and other locations.
    (Note: Each passenger is permitted to have only one plastic bag.)

Liquids subject to inspection

As these liquids will be confiscated at the screening area, please review this list in advance.

Common Examples of Prohibited Liquids

The illustrations above are items about which passengers often inquire.
There are many other prohibited liquids. For further details, please see the list of liquids below.

Liquids purchased at duty free and other shops after departure procedures, including screening, have been completed can be brought on board the aircraft.

Liquors, cosmetics, and other liquids purchased at duty free and other shops after departure procedures, including screening, have been completed can be brought on board the aircraft regardless of the above restrictions. (Liquids exceeding 100 ml can also be brought on board the aircraft.)

However, passengers with connecting flights at overseas airports may be subject to carry-on liquid restrictions at security checks at their connecting airports. Please purchase liquid duty-free items in the duty-free area of your final connecting airport.

For more details, please contact your airline.

Reasons for the duty-free exemption

To ensure safe operation of aircraft, all passengers are asked to undergo security screenings before boarding.

The area passengers enter following the security screening is called the Sterile Area and has been certified to be secure.

All passengers in the Sterile Area have already undergone baggage screening, so this area has the same level of security as the aircraft cabin. Passengers are treated as though they are on board the aircraft, and therefore are permitted to make purchases.

To facilitate smoother screening:

We ask that you familiarize yourself with the carry-on liquid restrictions and prepare these items before leaving your home.
Also, if you will be carrying liquids on board the aircraft, your security screening will be much smoother by placing the liquids on a separate tray before passing through the X-ray machines.
