RPT - Regular Public Transport
Covered in the Aussie Regs - basically scheduled airline transport services.
"the purpose of transporting persons generally, or transporting
cargo for persons generally, for hire or reward in accordance with
fixed schedules to and from fixed terminals over specific routes
with or without intermediate stopping places between terminals"
If you like I could pass on the links to our regs that relate to it.
You could read up on RPT and if you can understand the rules explain them to the rest of us.
