Make photocopies of your passport’s identification page and of your identification cards, and keep the copies separate from the originals when you travel. Leave a copy of your itinerary with someone at home so they can contact you in case of an emergency.
There are restrictions on what you can take on-board the aircraft:
Do not display large amounts of money or expensive jewellery in public; use a money belt or a case with concealed sections for valuables.
A person of less than 18 years that travels alone or with one parent, or another adult, must be provided with documentation certifying that both parents have authorized the trip.
