The last I heard was that the shopping mall including the duty free shop, bar and food outlets are going to be cleared out and the area is to become landside offices. This area was only built and opened in 2000 after the check-in area was moved to the new terminal in 1999.
The carpeted area beyond the shops will remain open and will receive passengers from the new departure lounge via the existing pier. Costa Coffee and the upstairs coffee shop will remain open.
