I've never actually seen these so called 'economies of scale' that big management companies proclaim benefit the owner. It could well be different in the large cabin market. But in the small over saturated end of it the owner doesn't seem to benefit at all. And as for the magical 'put it on our AOC and make you a profit' line. The dry rates that I've seen paid to owners over the last few years are poor. If the owner had a firm grasp on their costs and were honest with themselves(which is difficult as said management companies do their best to hide it) they would realise the rates they're getting don't even cover the hourly costs never mind the depreciation all these hours are incurring.
