The protest, organised by the "Airport out, Lisbon improves" platform, brought together citizens from the neighboruhoods of Areeiro, Alvalade, Campolide, Campo de Ourique, Camarate, Lumiar, São João da Talha, who with posters and slogans shouted against the inaction of authorities.

Near the exit of the Airport metro station, citizens demanded the end of night flights, the non-expansion and closure of the airport, in addition to the urgent construction of the new Lisbon airport outside the city and a new green lung in the city.

Sérgio Morais, from the platform, explained that the protest is related to the announced expansion of Humberto Delgado airport, recalling the latest news in which "it was indicated that the works will cost 300 million euros and last three years for a structure which is declared to be provisional".

"We demand several things, but the main one is that this airport has to move to the location of the new airport. We are residents affected by this airport and expanding is a completely scandalous thing", he highlighted.

According to Sérgio Morais, and according to figures from the Independent Technical Commission "depending on the measurements, there will be around 300 to 380 thousand people affected" by aircraft noise, including parts of the city of Lisbon and areas to the north such as Camarate, Póvoa de Santa Iria and Loures .

Sérgio Morais says that the noise caused by planes means for citizens in these areas "poor sleep, interrupted classes, interrupted medical appointments, the smell of fuel and high blood pressure also related to the noise".
