Top 30 airports in the world - An Analysis by CAPA

I was looking for a list of the top 30 airports in terms of passenger numbers and came across this article by the Centre of Aviation (CAPA) about "The world's top 30 airports: a disparate grouping".  (click here for the article)  The list above is from the article.

The following a listing of the various aspects that it examines in the analysis of the world's top 30 airports in 2010.
- how the list of the top 30 airports have changed over the last 20 years and a breakdown by region
- It looked at various subgroups, primarily international and primarily domestic, I was not surprised to read that DXB, HKG and AMS was 100% international passengers but it was interesting to note that London Heathrow (LHR) was 94% international passengers.
- It examined hub dominance and provides percentages of hub carrier at their hub airports.  These numbers are not easily available for airports which are located outside the United States.

Hub Carrier's share of total airport traffic
Singapore Airlines / Singapore Changi Airport (SIN) 34% (48% with Silkair and Tiger)
Emirates / Dubai Airport (DXB) 59%
Lufthansa / Frankfurt (FRA) and Munich (MUC) 63%
British Airways / London Heathrow (LHR) - less than half

- It also talks about Low Cost Carrier Traffic and provides numbers for legacy passenger traffic for various airports.
- There was also an analysis of carrier and alliance dominance at the top 30 airports.

If you want the actual numbers, I would suggest going to wikipedia and look at the article "World's busiest airports" click here.  The source for that is probably Airports Council International (ACI).
