The flights to Wroclaw and Gdansk in Poland, Riga in Latvia and Cluj-Napoca in Romania will operate from the beginning of July, running throughout summer.
Wroclaw will operate twice a week, and Gdansk, Riga and Cluj-Napoca three times a week.
Return fares start from £83 to Wroclaw, £85 to Gdansk, £94 to Riga, and £95 to Cluj, and customers can book from today (27 April).
BA’s flexible booking policy offers customers no change fees or a voucher exchange for bookings made for travel before the end of April 2022.
Neil Chernoff, BA’s director of network and alliances, said: “It’s great to be launching new routes as we listen to our customers and assess where they want to travel.
“We know these four new destinations will be popular with people visiting friends and relatives, but they also offer great city breaks, when the time is right, with flights that head out just before the weekend and return on Sunday.”
All flights will be operated by BA’s short-haul Airbus fleet.
BA will also launch a new summer service to Perugia on 28 June. This was due to start in 2020 but was delayed due to the impact of the pandemic.
