Rex are doing OK as far as profitability is concerned, but as others have alluded to - the Saab 340 is an ideal aircraft that has no upcoming replacement at all, which is really weird. I can easily forsee the entire worldwide Saab 340 fleet ending up in Australia being cannibalized for parts and working for another 10 years at Rex and other operators as well. Just like all the entire fleet of Fokker 50/70/100s will possibly.
Back on topic - there is a Skytrans Dash 8-100 that might just pip the other suggestions as far as age is concerned.
