so where would they fly on a RPT basis ?
You'd avoid the mess at SYD, BNE & MEL like the plague.
With 36 seats you could only offer a service comparable in prices to QF & VA, but without all the delays, parking hassles, security, +DELAYS, DELAYS DELAYS etc.
Perhaps Essendon or Moorabbin to Bankstown ?
Getting to western Sydney, which think I read is now the 4th biggest metropolis in Australia, is very time consuming.
Security charges from these airports though would be very high as they would be the only ones paying for it & so would need lots of flights everyday to spread the cost.
If on the other hand they somehow had their aircraft "recertified" by manufacturer at under 20,000 kg, they would not require any security.
