With Qantas announcing several new routes that may open up with the arrival of their 787 aircraft - how does an airline go about preparing for these flights e.g proving flight. Is this done using an actual aircraft with real crew / weight to simulate passengers and baggage / when to serve meals etc etc, and how many flights are done before actual revenue flights begin ? It seems all talk at the moment , but has anyone flown a 787 Perth non stop to London or Sydney to Chicago ? Curious !
