If I have a child over 18, will (s)he be covered under my family policy?

Generally, any traveller over 18 years old is classified as an adult; if you have a family policy, you will only be able to include children up to the age of 18 years old. Any children over this age limit will need to take up a separate policy. Some insurers, however, increased the age limit up to 25 years old if the traveller is a full-time student.
