The sustainable mobility law will have to return to the Congress of Deputies after the People's Party (PP) introduced some eighty amendments during its vote in the Senate on Wednesday, where it holds an absolute majority. Among the changes the PP has put forward is one that has set off alarm bells at Aena: the freezing of airport fees. In a statement released Wednesday night, hours after the Senate vote, the Spanish airport operator warned that the proposal jeopardizes the investment plan announced for the 2027-2031 period of almost €13 billion. Specifically, the €9.991 billion corresponding to regulated investment, which also affects El Prat Airport.
