I wonder if there is a breakdown somewhere of the 5.7m pax in 2007. It will be interesting to see routes and pax numbers at that time.
I would suggest potential is much higher than another 900,000 quoted, as the region has since grown in population. We have endured a recession over recent years, which has hit growth, but it was estimated at the time of the Masterplan, the Airport would reach 8m pax by 2025.
