Airport management believe 30m pax could be reached 10 years earlier, by 2020. If new runways in the south are delayed slightly, they are predicting 23.5m pax by 2015. Tracked monorail system planned for new term plus replacement 3000m runway set 950mtrs to south of existing. Lots of new stands etc. Phew!!!
Wait for the nimbys to come out fighting.
