That said, the 'Singapore' bid also has some promise if VA ends up tying in nicely with the SIA network into/out of Australia. I guess this would allow them to remain full service as well, and perhaps over time even take it up a notch to match SIA. Star Alliance could eventually be on the horizon and in terms of a full-service road to recovery I think aligning with SIA would be the strongest choice.
What I wouldn't like to see is Etihad taking any control, as they have shown time and again that they can't manage nearly anything they touch – Air Berlin, Virgin Australia, Jet Airways, Darwin Airline and Alitalia. Would also like to avoid multiple owners as VA's last decade has shown that it just becomes self-serving to the owners interests and in a decade we'll be at this stage again.
It's not "SIA" directly, but rather their parent company Temasek instead. Which may potentially do better than SIA proper at managing overseas investments.
Etihad has a terrible track record at investments, but SIA overall are not much better: Air New Zealand/Ansett, Tiger Airways Australia, Virgin Atlantic and now Virgin Australia. All four were dismal failures for SIA.
The only investment that both Etihad and Singapore has done "moderately" reasonable at best is the Air Serbia and Vistara (India) investments respectively.
