I was told to buy insurance as I bought this ticket on deployment and the dates of when we would be in port are not always accurate. As the time came closer, I cancelled my flight because I was told I am going on a military flight instead. I filed the claim, providing the appropriate information, only to find out they denied it because it was not involved in their three checked boxes of reasons a flight would typically be cancelled (death of a family, unexpected injury, sickness, etc.)
BIGGEST WASTE OF MONEY. DO NOT BUY INSURANCE THROUGH THEM IF YOU BUY A TICKET THROUGH EXPEDIA.COM
