Methinks, the first flight should be minimum 8-10 weeks away. That means end of July - mid August.
I'd add about a month to that to negotiate the Chinese bureaucracy and then we're close to being on the same page. I would not expect to see commercial flights until September (possibly even later), although aircraft deliveries and demonstration flights for the AOC are possibly going to be scheduled before that. Again though, subject to various external factors aligning correctly.
With regards to Facebook and other social media tools, the Chinese members of our team cannot even access many of them, so it is quite definitely not going to be our primary focus for anything. Our intention is to maintain a low profile until we have specific dates and plans in place and then pursue our marketing strategy. Facebook, like PPRuNe, is simply a means to engage with interested parties in the interim.
