They never said they were buying a new fleet - the money will help get the existing grounded aircraft back up in the air. EY have probably found that if there is any chance of getting some cash flow, they need to get those aircraft back up and running to have a viable network.
Still doesn't mean that you'll get someone buying it though. But the AFR reports that one bidder was keen and shown the door, so that's interesting.
I really don't get how it can't be a viable airline on its own. Before the 737 saga, they managed to run a cash flow positive operation.
The SAABs are old but if looked after they can still last another 10 years. That is more than enough time to start looking at fleet replacement.
What makes them such a poor buyers prospect now that wasn't the case 10 years ago?
