Whilst I read that the search area might move downstairs, I wonder how many more shops are going to be fitted into the original area? It would be difficult to change the unending corridors with no travelators and the time taken to get to the gates.
The existing search area will become the start of the airside lounge. It will continue into the new build above the new entrance hall in the area which is now the bus and coach station. It will continue and cross the existing ground floor entrance. The existing Duty Free shop will be modified to allow access to the new pier. New seating areas will be gained as well as many more shopping outlets. The existing pier to the eastern apron will be puffed out on either side to allow gate seating.
