"Catch is who's AOC could they go on ?"
Whoever wants to blow a year's work and quarter of a million to get them on. Of course CASA would assist this expenditure of time and money in any way possible. Then another quarter million for ADS-B and whatever else needed to be done, training crews etc. That's assuming that the operator already had a high capacity AOC. Double those numbers for a start up.
For what - four or five hours a week carrying liquored-up supporters around with the team? Do you armchair airline tycoons know what it costs to run a Bae-146 on a low utilisation maintenance schedule? Per seat, about double a B737-400.
Same for cargo: per kilo about double the Boeing, assuming similar distances flown.
It is a great niche aircraft, but flying between large airports is simply not its niche. Give it gravel or 1500 metre strips and there is nothing else in that size range other than its mate the Avro. Cobham have that market stitched up already and they won't concede business easily.
If sports groups were worth doing, the brokers would be right on to it. Vincent would have done it. Alliance could be doing it. Jetgo would get the small stuff. While there is a lot of talk about teams and special interest tours, it rarely amounts to much because there is usually an acceptable way to move people more cheaply on the main carriers.
Some AFL clubs are making enough to buy their own aircraft and run them privately. Private 'club' flight operations do happen in the USA, so someone with very deep pockets could probably make it happen here if they thought that the advantages justified it.
