TCAS FAN: You certainly have great knowledge on the issue. It seems everything from the toilets to the frequent departure lounge refreshes have seem investment yet the most airside has seen is a couple of solar powered taxi lights that last time I checked were not even there any more. I think anyone who uses LHR, especially T5, would be forgiven for thinking that BAA/HAH are focused on retail rather than transport infrastructure.
I guess SOU is kind of stuck with a HAH/BE combo who both lack any real drive. Still, I guess its a better way to do business than to invest 40mil on a new terminal when two planes on the deck constitutes a busy day
