In 2019, Athens International Airport S.A. (AIA) initiated a five-year programme for the implementation of the Action “Evolution into a high-performing node within the European Air Traffic Management (ATM) Network”. This Action (no 2017-EL-TM-0158-W) is co-funded by the European Commission, under the programme of “Connecting Europe Facility – Transport Sector”, which concerns EU's priority for the creation of the “Single European Sky” (SESAR).
