Planned works on the main runways will force the airport to operate with a single runway, significantly increasing the number of flights passing over Castelldefels. Local authorities argue that the current environmental impact assessment fails to account for the real effect on residents' sleep and well-being.

Key demands include a total night-time closure of the airport during the works and technical changes to redirect take-offs towards the west. The Council is also calling for a real-time noise monitoring system to ensure immediate corrective actions are taken if noise thresholds are exceeded.
