How to Stow Your Baggage in the Cabin

  • Carry-on baggage is restricted to items that you yourself can stow either in the cabin stowage compartments or under the seat in front of you.

  • When stowing your baggage in the shared overhead compartment, please make sure that it will not slip out of the compartment when it is opened.

  • When stowing baggage under the seat in front of you, please make sure that it is pushed back as far as it will go. If your baggage is not stowed properly under the seat, it could slip out in the event of a sudden impact and injure you and other passengers.

  • Leaving baggage in locations where it might hinder an emergency evacuation such as in the aisle or near the emergency exits is prohibited by law.

  • If there is no seat in front of you (e.g., you are sitting in front of a cabin monitor or behind a partition), you cannot place any baggage down by your feet.

  • If you would like to bring a larger piece of baggage on board which is unlikely to fit inside the cabin stowage compartments or under the seat in front of you (e.g., a painting or musical instrument), you will need to purchase a ticket for an additional seat.

The diagram shows suitable and unsuitable ways of stowing baggage. The only suitable ways to stow baggage in the cabin are in one of the overhead stowage compartments or under the seat in front of you. Locations aside from these are not suitable for stowage.

Please stow your baggage under the seat in front or in the overhead compartment.

The following situations may occur if baggage is not stowed properly.

Cause Injury

Your baggage may fly out of your hands in the event of a sudden impact, etc., and injure another passenger.

Hinder Emergency Evacuation

Baggage may scatter across the aisles and the areas near the emergency exits, and could thereby hinder an emergency evacuation.

Prevent You from Bracing for Impact

Having baggage on your lap will prevent you from bracing for impact in the event of an emergency.

Restrictions are imposed on carry-on baggage by certain countries or regions.

The use of fire on board aircraft is restricted.

Carry Bags

Due to limited storage space in the cabin, carry bags may not be accepted for carry-on even if they meet the stipulated size.

Large tripods with a length exceeding 60 cm when folded are not permitted to be carried on board.
