Listening to the radio in the car today and, changing channels came in half way through an advert 'T5 is working'. I heard how they had spoken to n people yesterday and how quick part of their transit through T5 had been. Personally, I would have waited to do the 'Working' campaign until after all the flights had transferred. They only need a small amount of disruption before it's complete and all this money will be down the drain and they will have more ridicule in the press.
I have not had to use T5 yet but the process of delivering my sister there five weeks ago revealed that many signs on the roads outside as much as those inside, were not in place and that staff with official uniforms on did not know where a particular place was and showed zero interest in trying to help me locate it. (Waving her hand) "It's over there ..." It wasn't and I was not impressed.
