I have never heard anyone say IC was helpful in getting them rebooked. AFAIK, they are based in T&C, and not subject to the same requirements as US airlines might be. George would certainly know more. Hopefully they will help get you on their next flight.
We like the new Silver planes, and find them a good option. Neighbors have been burnt by them, however, and sworn never again. Cape Air is reliable, but at a price. American has been offering terrific deals on their direct flights, and that has become the most popular option. But, of course, people have miles they want to use.
