Went through again this week. Better than last time, but not great.
From my 2 recent experiences, the bottlenecks are not the service lifts. But the lack of available working scanners. That takes the queue back to the lifts.
Get the scanners in place with the right manpower so that the lines are open and it ‘should’ work fine (providing this new technology is reliable day in day out).
Listening to a member of the security staff talking to enquiring customers. He was cockily talking along the lines of becomming the UKs No 1 airport for passenger ease and speed of baggage security scanning clearance come the summer. Was probably a Villa fan.
