As you know Kennmore has two divisions: the float plane division which is one of the largest in the world, and the caravan division.
I am not sure how many they have, but the caravans are based at BFI and fly to the San Juans and Port Angelas. They just bought a couple of caravans from San Juan Airlines, who are based in Anacordas.
