The SEA Group manages the Malpensa and Linate airports under a 40-year agreement signed by SEA and the Italian Civil Aviation Authority in 2001. The Milan airport system consists of the following airports:
- Milan Malpensa, Milan's intercontinental airport, consisting of two terminals. Terminal 1, which was fully renovated following the completion of the restyling of the Schengen area, serves a wide range of domestic, international and intercontinental destinations and is home to a diverse assortment of stores, restaurants and services which meet the needs of all of the airport's passengers.
Terminal 2 is easyJet's main base of operations in Europe, serving a broad network of destinations. Following the extension of the rail network, which already connected Milan with Terminal 1, Terminal 2 can now also be reached by train.
- Milan Malpensa Cargo is the nerve centre of inbound and outbound cargo distribution in Italy. Nineteen all-cargo airlines operate out of Malpensa Cargo.
- Milan Linate primarily serves frequent-flyers travelling to destinations in Italy and the EU. Just 8 KM from Milan city centre, Linate is truly a city airport, with structures and areas dedicated to business and shopping. Ground was broken in 2017 on the restyling project, which is to involve thorough renovation of the entire airport.
- Milan Linate Prime, an airport managed by SEA Prime S.p.A., a subsidiary of SEA S.p.A.. Dedicated to general aviation, its services and facilities provide significant added value.
Finally, through SEA Energia (a wholly-owned subsidiary of SEA S.p.A.), the Group owns two co-generation plant, mainly meeting the energy needs of the Linate and Malpensa airports, providing electricity, heat and district cooling.
