Incidentally, re. my mention of the possibility of a/c stands to the east of T2: I seem to recall seeing a plan which effectively made T2 double sided for part of its length i.e. providing contact and not just remote stands. Whether that was part of an official option or more a sketch by someone making a suggestion, I don't remember. That space between the vehicle exit road from departures level and the T2 structure is a car park at present, for staff I assume.
The current favoured plan 'allegedly' involves extending T2 in both directions, including into the car parks at one end and linking it up to T1 at the other. C Pier at T1 is to be demolished to finally get rid of the PITA bottleneck around it and T2 will also have two piers added so aircraft will park on those rather than nose in to the terminal as is currently the case.
