The Spanish airport authority Aena is planning to invest around €1.5 billion in remodeling its Adolfo Suárez Madrid-Barajas facility as part of its 2022-2026 Strategic Plan.
Recently approved by the Aena board of directors, the operation consists of merging Terminals 1, 2 and 3 and expanding Terminal 4 and its satellite 4S to optimize the overall functionality of the airport while raising passenger capacity from 70 to 80 million.
