The number of air transport movements is important in connection with the agreements that have been made within the Alders Platform regarding the growth of Schiphol. According to these agreements, the maximum number of air transport movements is set at 580,000 in 2020, 70,000 of which must take place at Eindhoven Airport and Lelystad Airport. In 2008, the year that the Alders agreement was made, the number of air transport movements was 425,000. Due to the economic crisis in large parts of the world, this number decreased to less than 390,000 in the years 2009 and 2010. In 2011, traffic volume increased again to 420,249 air transport movements. This growth continued in 2012.
In 2012, the number of air transport movements in commercial traffic increased by 0.8% (8.8% in 2011) to 423,407. The number of air transport movements with passenger aircraft increased by 0.9% (9.1% in 2011) from 404,321 to 407,864. The increase in the number of available seats was slightly lower at 0.7% to 63.2 million. The average seating capacity remained virtually the same at 155. This can be explained by the fact that the higher number of air transport movements were flown by the same type of passenger aircraft as in the previous year.
The number of air transport movements carried out by cargo aircraft decreased by 2.4% in 2012 (+2.1% in 2011) to a total of 15,543 movements. The average maximum take-off weight of these aircraft fell from 328.6 tonnes in 2011 to 324.2 tonnes in 2012. The average size of cargo aircraft used was smaller.
