Trip cancellation insurance is a smart thing to buy for travelers that think that there may be a change in travel plans or for anyone that is buying an expensive international plane ticket. There can be small but significant differences with trip cancellation insurance when you are dealing with different travel insurance companies. Make sure to understand exactly what you are being covered for before purchasing any kind of travelers insurance. Make sure that any payouts given from the insurance agent are for real money not vouchers for future use. Look for trip cancellation insurance with the travel agent that is preparing your itinerary.
