Viscount,
I think you are being overly negative, but here goes.
You state regarding China 'we have been here many times before'. To my knowledge, this is the first time a mainland China carrier has given solid intentions of operating a MAN route. Air China applied to the CAAC in 2009, but never formally announced an intent to start flights.
Hainan Airlines have publicly stated they will start MAN flights. Im on a mobile so cannot link, but seek and ye shall find, the press releases are not hard to find and it was only this month the quotes were said from the vice CEO of Hainan. When the airline has stated intent to start for the first time, im not sure just how to quell the doomsayers.
In regards to Summer 2015, well, lets not head for the razor aisle just yet, Summer 2015 is still 7 months away, and until January, nothing is off the table. As for Jet2 ending CDG, locos shuffle routes all the time, and its not as if CDG is left unserved. Again, step away from the razors
