It is true only for the feeder aircraft like 737/757 and large part of 767/A300 fleet which are mostly oriented for overnight feeding in and out of hub. Longhaul freighters are typically flying round the clock, I believe CargoLux had one of the highest average utilisations in the industry ca 17 hours per day.
