Singapore should take back the Tiger AOC and rebrand it as Scooter.
A Scoot Domestic fleet with 20-30 aircraft would be sustainable, without Virgin.
Its certainly a option. Scoot is in the progress of upgrading its CEO to NEO and will have available aircraft.
They could base it in Sydney and take on a few hundred million in incentives.
Scoot is now run by Campbell again, so most certainly possible.
