ANA (ANA Aeroportos de Portugal) is the company that manages Portugal's main airports, including Lisbon Humberto Delgado, Porto Francisco Sá Carneiro, Faro, and airports in the Azores and Madeira. Since 2013, ANA has been owned by the French group Vinci Airports following privatization.

ANA is responsible for airport operations, terminal management, and infrastructure investment across its network. The company has been at the center of Portugal's long-running debate over a new Lisbon airport, with plans for a new facility to relieve capacity constraints at the current airport, which is located in the city center.

Passenger traffic at Portuguese airports has grown significantly, with Lisbon consistently ranking among Europe's fastest-growing airports. ANA's investment decisions and concession terms directly affect flight capacity, passenger experience, and connectivity for residents and tourists.
