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
If you look at artists impressions for T2 in the late 80s you will see a link between these two locations. But it was deleted during the "value-engineering" phase...
This link will help during the projects that FlyZB outlines, but will also benefit the flexibility of terminal allocation later, especially where the peaks of terminal useage are not simultaneous.
