Just opening this thread back up.
I've been trying to get ahold of One Air for the past 2 weeks and it's proving to be as difficult as getting an answer from a politician. I managed to get through to a reception lady three times, having to leave a message as this mysterious figure 'Cian' seems to always be on a conference call and he'll call me back after - which has yet to materialise.
It's difficult to rule out the ATO, as it's a good price on a nice fleet and I've spoken to two past students who have highly rated them.
Does anyone have any more information on them or who are currently studying there?
