From my point of view ( pointy end U/M ), having done two sectors now with London based Cabin Crews,they are going just fine. As you would expect they are not at the same standard as the Syd. based crews but hey, they are not very far off. They are extremely enthusiastic and because of this I think that in a relatively short time frame ( say a bid period or at the most two ) they will be offering a superior product. The only concern that I have is for their health if the Company starts to operate them on LHR/SIN/FRA/SIN/LHR patterns, as no doubt it will.
I wish them all the best.
