Even the best laid plans go for a toss sometimes—we’ve all probably experienced this. When it comes to international travel, this can prove expensive, and this is where trip cancellation insurance can come in very handy. For example, you really cannot take any action against unforeseen circumstances such as a terrorist attack at your destination. For the discerning traveler, travel cancellation insurance is a wise investment.

Often, a trip cancellation or interruption clause in the travel insurance ensures that you can get back the maximum amount shown in the Confirmation of Coverage if the planned trip is canceled due to the reasons that are spelled out in the travel insurance policy document.

For example, the plan might reimburse the non-refundable costs of your trip if you are transferred by the company to a different location before the plan period, and you need to relocate or if you are laid off by your employer. There can be accidents involving you, or your travel companion, which requires hospitalization. You may cancel the trip due to the death of your host in the destination country too.

Other common covered causes include natural disasters which result in flights being canceled for at least 48 hours, or natural disasters occurring at the destination city which makes it impossible to go there. A strike that causes cancelling of all flights for an extended period can make it impossible to travel. As always, it is best to check the particular coverage that your plan offers.
