I'll cross my fingers that they choose the A350 rather than 787. I have yet to feel comfortable in one of the latter.
However my biggest fear is the number of A321s they buying. Only people from Europe seem to begrudgingly accept them and that is due to the appalling way passengers there allow themselves to be treated. Of course there was one favourable comment and I will not offer a prize of US$100 for guessing who made that. I hope that the A321s are all confined to China service or transferred to UO but there just seem to be too many of them for that. I honestly don't understand it. Buying them by the dozen just seems to be the action of a suicidal premium airline. East Asia is not Europe or continental US. Distances are far greater. People here still seek quality and many can afford and are willing to pay for it.
