The three mega-airports show different growth patterns in their passenger traffic. DFW initially grew rapidly, but achieved a peak in the 2000s. This implies that DFW has reached its market potential. A similar observation applies to Kansai, which has experienced limited growth since its opening in 1994. It was set to provide additional regional capacity to the Osaka Airport, which focuses entirely on domestic traffic. The situation is very different for Hong Kong which has experienced since its opening in 1997 a continuous and rapid growth, more than doubling its traffic.
