The sooner they turn the whole of upstairs into airside the btter, then there will be only the need for one serendipity site, along with 1 world news. chances of more shops or better facility's. People will have to pass through security to get to the facility's and therfore should stop the straddlers turning up at the gate so late.
Is there any reason why the serendipity is shut and is it the one in the departure lounge or the one by info too?
