The area to the right of the Silverjet lounge is still the ghost of the former old departure lounge complete with abandoned shops, the bar and restaurants. The old duty free shop also remains. Add this to the Silverjet lounge and you have a large area that is ripe for redevelopment but not for an executive lounge due to its distance from the check-in area.
At the moment the old Boots shop is used by WH Smith for storage.
