Imagine if the new "G" apron was increased in size, after sercurity checks in the main terminal you could then be bussed over to the souhtside!
Why not just increase the size of the current Apron (which is going to happen any way). "My understanding is that the southside will be developed for freight ops maybe aircraft maintenance one day". You can't just bus passengers over to the otherside of the airfield, its not as easy as that. How are you going to get luggage across there. You can't take passengers across the runway and you can't take them out the barriers because they are then leaving a "Restricted area", which means they have to be searched again. Same with luggage, once it has crossed the RZ line it would then have to screened again.
