Looks like the front of the old/arrival/current terminal will all be "woven together" into a much more pleasing external appearance. The "Tin" should vanish thank god.
Also, it seems Security will move down to ground level, with 18 new passenger lanes. Seems to be possible because of the infill at the front linking the old/new terminal. Will they have any staff to man it though. The old terminal will then house 8 international and 1 domestic baggage reclaims.
The road improvements in the CTA do seem, on paper, to be reasonable. See plans on the website. These plans definitely seem to be concentrating on improving the passenger experience with modest pax expansion, as opposed to LBC, who seem to want huge passenger expansion at whatever cost.
