The airline will launch the year-round route, which will operate six times per week, on September 1, 2019.
Bergamo airport is located 45 kilometres from Milan and is the nearest gateway to the key destination of Lake Como, as well as being close to the Italian Alps.
Adam Carson, BA’s managing director of Gatwick, added: “Milan Bergamo adds another exciting destination to our Gatwick network and is perfectly located for a city break, a summer visit to the lakes or even a skiing holiday in the Alps.”
The Gatwick-Milan Bergamo route will operate every day of the week except for Saturday.
BA is also increasing the frequency of flights from Gatwick to Cancun, which will move up to five per week during the winter season.
