EUROCONTROL, as the Network Manager (NM), provides operational stakeholders with the most accurate picture of past and future pan-European air traffic demand from several years ahead until the day before operations. This also includes environment data, analysis reports and tools (SAAM and NEST).
All this information is managed by and can be accessed via the Demand Data Repository (DDR). Access to the DDR is restricted (see access conditions below).
Access to the DDR portal is restricted to air navigation service providers (ANSPs) and airline operators (AOs) within Europe, on the basis of approval of a licence agreement and formal acceptance by EUROCONTROL. Airlines are allowed to download (historical or forecast) traffic data for their own fleets only.
As of June 2019, we no longer provide access to the DDR portal to students.
