We had a positive experience when canceling our November trip which we had booked through Expedia. I'm sharing because I think a lot of us question whether or not the insurance is worth it. Because of my husband's health it was necessary to cancel so I contacted Expedia and they immediately credited my Visa for the resort fees. We were booked at the Radisson and they allowed cancellation without penalty for up to 30 days prior. Airfare goes in accordance with the airline policy. So in the case of Jet Blue they issue a credit good for one year from date of purchase. In most cases, this would have worked but with my husband's condition we would not be able to use the credit within a year. So this is where the insurance kicks in. I notified Berkely (Expedias provider) and they forwarded a claim form which the doctor filled out. Once submitted I received an email acknowledging receipt and less than 2 weeks later an email stating the check was being mailed. For about a $100 investment we were totally reimbursed and we were totally happy!!
