I have just seen the development plans for Manchester. The development plan covers the development of the airport upto 2020.
The first stage of development is to extend T2 and to extend T3 from 55, both these extensions will allow aircraft stands on both sides of the pier. The final part of the first development stage is to have a satellite pier on the 230's and 80's stands now with an underground link. this development should be finished by 2010.
The rest of the development upto 2020 will allow another satellite pier which will be situated where the fuel farm and the cargo sheds are which will be connected to the first satellite link. To make room for this new satellite and to ease congestion Charlie pier will be demolished and Bravo pier realigned. It is rumoured that the satellites will be connected to both terminals.
