I'm not sure why you posted this, if it doesn't apply to posters in this thread.
That said, CSA is very good about getting you to your destination. I always assumed they had special deals with some of the airlines, because they work hard to get you where you are supposed to be as quickly as possible. If you have to cancel your trip, yes, they will give you back what you paid, or in the case of Southwest, where you get a credit, they don't, unless your credit expires within so many days of your trip..then they will give you the value. There are several types of policies even within each brand..you can choose to pick one of them that includes carrier default, although I try to stay away from the carriers that may default, or go out of business.
CSA is excellent at paying for your hotel room (they paid up to $150 a night for us), when returning from Disney, if there is a wait for a plane, because of weather (or if there is no room) as well as other costs.
CSA also pays the difference between what your insurance company pays (if you have insurance) and what the medical bill cost you, if you have a medical problem. One gal on cruisecritic told about missing her ship at a port, and she was flown at no cost to her (she paid and was reimbursed) to the next port.
There are a lot of good reasons for insurance, including an ill parent.
People have to do what makes them comfortable. You do get between 10-15 days to look over your policy after you pay. You also usually have to purchase it before final payment.
