Traffic hasn't really increased that much - used to hold but then get 6-7nm spacing on finals - it's just the location of the new terminal which makes using the eastern runway impractical, so easier to create a new one. (???)
Will it be 2 landing 1 taking off, or mixed-mode on the third runway or....? Also is there any particular reason we always got 6 miles on finals or was it due to pilots not liking less? I gather radar performance and runways allowed the use of less because it occasionally happened.
Quite disappointed I was never able to visit the tower while I was out there, only got as far as KK.
