God forbid they have an aircraft available to do charters! They are still doing their RPT and they have an aircraft available to do charter work.
Look elsewhere on this thread and you will see that they have been doing a lot of Immigration and election related charter and they are opening up the Brisbane-Townsville-Denpasar route soon (subject to regulatory approval).
From what you are insinuating they shouldn't use their spare capacity prior to the new service to make a bit more revenue.
Sounds like you would work operations like an Army quartermaster " That's the last one I've got, can't give you that one, somebody else might want it"
