Traffic stats
The significant figure generally used to compare airport's throughput is terminal pax, and so we have to take 24.85M as the September rolling figure. Still very healthy and an all time record. I think October will fall just short of 25M, but we'll see that well within the calendar year. From there you need just 4% growth per annum to reach 30M in 4-5 years time.
The figure which jumps out is the 186,000 rolling ATMs. This has leapt up this year, and if the winter schedule is as busy as I am hearing, we will soon be back to 200,000 ATMs, a figure not seen since well back in the last decade.
