A300Man,
Well noted, I actually made a post before I slept and I woke up at around 3:30am, I have been like this for quite a while no matter how late or early I sleep I always wake up this early.
WRT Vietnam even if QR relied solely on European traffic they will do well. Currently the existing Euro services are flying packed and since supply is so small ticket prices are expensive. If QR enters the market they will have no EK or GF competition and if loads are an issue they can always combine the route with another.
Over the past year the CAD has been renogitiating ASA's with many countries to allow QR to increase frequencies and to allow QR to get 5th freedom rights.
I also intended to say earlier that the A340-500 is a very heavy aircraft and is quite expensive to maintain, the fuel burn is unflattering too. Any use of the aircraft on routes shorter than 5500nm would be overkill. So if QR would not fly to the US the A345 would make no sense at all.
