MAN777, I agree with you in certain respects but bulldozing T1 and starting again simply isn't an option. The only way this could be achieved is by constructing a temporary terminal first or by building a completely new terminal on a different site and then demolishing T1 altogether after that and leaving that site empty. Both are extremely costly and whilst I agree that it would be the only real long term solution to certain problems, the money simply isn't there to undertake a project of that size. The demolition of 'B Pier' in itself will cause an incredible amount of disruption. So much so that the airport will probably have to spend 15m on a link between gate 22 in T1 and gate 202 in T2 just so T1 flights can use T2 whilst 'B Pier' is rebuilt. That in itself will cause minor problems when you consider the walking distance between say the current airside food village in T1 and gate 205 in T2. Anything on a larger scale is just a no go.
GavinC... T2 'West Pier' will be extended so that gates 216-219 will be part of the terminal and connected by airbridges. This scheme has already been given the go ahead and will start shortly. This will allow gates 201-205 to be used by T1 carriers without affecting the T2 operation too much.
