I think the walk from south security to the south lounge in T5 does detract from the premium experience. It’s a hike with too many escalators and even on the first occasion when you realise the length of the walk for the direct distance you’ve covered it’s a surprise and after that just annoying.
We should’t be surprised at BA cow-towing to BAA, they always have which given that they are BAAs biggest customer says there is something wrong with the relationship.
I can still remember being told to turn up earlier to queue for security after the ridiculous liquids restrictions were brought in. When I asked BA why they weren’t demanding that BAA operated more efficiently, extended security areas and ripped out shops to do it my questions were met with absolute silence!
I asked SQ the same question and on the next occasion I flew with them, I was provided with an escort through security and cleared it in three minutes; not something they could do for everyone but then high spending premium flyers are not ‘everyone’ they are special and need to be looked after!
