It's the most customizable travel insurance I've come accross, with coverage for short and very long trips, very high age limit (74), and a lot of smart features; customize it by yourself, I bet you couldn't find a better price around!!!
Probably the most famous travel insurance. Offers a complete default coverage. Are you leaving for a travel but you don't know yet when it will be time to get back home? WorldNomads allows you to renew the policy whenever you want, even at small day-steps, or to buy it after you've left your home.
