I am sure that is a consideration. The performance of a turbine Beaver is also not as much of an improvement as a converted Otter. Margins on transportation flights are thin. Margins on flightseeing are not. The company I worked for chartered a Beaver between $600-$700 an hour and a turbine Otter at double that. Seats for 45-minute flightseeing (through a national monument) were priced at $185-$250. 6 pax in an Beaver and 10 in an Otter.
