They appear to be struggling a bit on the Norfolk Island run with the F100's. They were to commence a Sydney/Norfolk Island service on 7th September to operate on Saturday & Sundays.
Startup date is now 28th September and then only on Saturdays.
From Brisbane they appear to be hauling a lot of day trippers.
On Sundays after they arrive on Norfolk Island from Brisbane they have to startup again and go an park on the end of the non-jet runway to allow ANZ/NJE flights in, and then at on Sunday evening startup again and taxi back to the terminal.
I hate to think of the maintenance cost of all those engine starts.
