The airport opened a peak time only Security Zone 2 last year which reduced the queues. The issue was that passengers had to follow the signs and leave the new terminal and re-enter the old terminal at the former SilverJet entrance. Once cleared passengers found that they then had a long walk to the main departure lounge and then equally another long walk if their gate was back by the exist of Security Zone 2.
This is far from satisfactory and shows the urgent need to get on with the building over of the bus station which will allow a much bigger security area to move downstairs.
