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.
