'Travel insurance' is insurance that is intended to cover financial, medical expenses and other losses incurred while traveling, either within one's own country, or internationally.
Travel insurance can usually be arranged at the time of booking of a trip to cover exactly the duration of that trip or a more extensive, continuous insurance can be purchased from (most often) travel agents, travel insurance companies or directly from travel suppliers such as cruiselines or tour operators.
Travel insurance often offers coverage for a variety of travelers. Student travel, business travel, leisure travel, adventure travel, cruise travel, and international travel are all various options that can be insured.
