Start with your passport: check its expiry date, as many countries require it to be valid for at least six months beyond your return date.
Check visa requirements for your nationality and for every transit country. Some destinations accept an e-visa while others need an appointment and extra papers, so do not leave this step late.
Keep copies of tickets, hotel vouchers and insurance on your phone and in your email, plus a printed set.
Add travel insurance that covers medical costs, baggage and itinerary changes, especially for destinations with high medical costs.
Finally, save key contacts: your hotel, the airline and our support team, so everything is at hand.
