Travel insurance can be a lifesaver! Trip-cancellation /interuption insurance (TCI) reimburses you for any non-refundable deposits or prepayments in case you're forced to cancel or change your plans at the last minute, due to an illness, an accident, financial default of airline, cruise line or tour operator resulting in the complete cessation of services or filing of bankruptcy, or any other unexpected problems. It also covers the added expenses of an early return if you suffer a mishap while you are traveling.
One of the most confusing aspects of travel insurance is the discovery of the specific pre-existing conditions that can void your trip-cancellation coverage. Some insurance companies are more liberal than others on this and some now waive pre-existing conditions.
Overall, consumers should read all the fine print (granted, not always easy) and ask a lot of questions. The more you know up front, the fewer hassles you will encounter if you need to file a claim.
