Correction to my previous post, the turnstiles are being removed, but replaced with another type. It seems that they want to bring the security fee in as a discretionary "fast track" charge on 1st May, however there is still opposition from the airlines I believe.
On the improvements front, work is to start on a multi-storey car park with 5 star hotel on the top soon. Planning permission has been obtained and it will be sited on the existing short stay car park. A covered walkway will be installed from the car park/hotel over the access roads and enter the terminal on the statue level. Also covered walkways are being installed airside for passengers up to stand 7, which will stop a lot of passengers getting soggy!!
