Spain approves Aena 13B airport investment plan, caps fee hikes at 0.33%

Spain's Council of Ministers approved the 2027-2031 Aeronautical Regulation Document, authorizing Aena to invest €13 billion in airports, with Madrid-Barajas receiving €4.477B and Barcelona-El Prat €1.765B. Fee increases are capped at 0.33%, below inflation, which may pressure Aena's returns but supports air travel growth. The plan signals long-term infrastructure commitment, though regulatory constraints could affect Aena's financial performance.
