surely you can have a FIFO contract with miners flying on RPT services with the general public filling the aircraft.
Maybe the mining co. wants high frequency say 25 miners per flight, so Jetgo can then sell the extra 11 seats for a profit.
Only catch is you can't avoid the security nonscience, that can be avoided with pure FIFO ops.
What about a route like MEL/WOL that was abandoned by QF link 5 or so years ago. Think QF did 2 flights a day every day using an old Dash 8-100.
