interesting idea
"2. Accept regional services from their town to Bankstown where the huge costs levied by Mascot airport are reduced off the air fares."
Bankstown costs way lower than Mascots & who actually wants to go to Sydney CBD anyway ? Something like 3/4 of Sydney population live closer to Bankstown than Mascot anyway.
Think there's currently a cap on RPT services into Bankstown. Is it 12/day ?
+ Rex wouldn't want to fly to Bankstown, as they are scared of being shut out of Mascot to be replaced by bigger aircraft, who pay much higher fees.
