Paris-Orly airport’s traffic is mainly origin/destination traffic. In 2017, however, connecting passengers accounted for about 6.8% of departing traffic, or more than 1.1 million passengers.
Over the last seven years, passenger traffic at Paris-Orly has been steadily growing, with record passenger traffic levels since 2013. There has also been a change in structure, with strong growth in European traffic offset by a fall in domestic traffic, particularly because of the cap of 250,000 landing and take-off slots attributable each year, as well as the impact of the TGV high-speed train on domestic flights. The South-Eastern LGV line was commissioned on 1 July 2017. This change has been accompanied by an increase of nearly 22.8% in the number of passengers per aircraft since 2009, with an average of 140 passengers in 2017, versus 114 passengers in 2009. During this period, the size of the modules used at the airport has constantly increased.
