British Airways is adding four short-haul routes to its European network this summer.
Wroclaw and Gdansk in Poland, Riga in Latvia and Romania’s second largest city, Cluj-Napoca, will be served from Heathrow.
All are established destinations served by rival Ryanair.
The summer-only flights start in July with return fares starting at £83 to Wroclaw, £85 to Gdansk, £94 to Riga, and £95 to Cluj-Napoca.
Gdansk, Riga and Cluj-Napoca will be served three times a week and Wroclaw twice a week.
BA last operated flights to Riga in 2007, and flew briefly to Gdansk between 1999 and the early-2000s. The airline has never served the other two airports.
The flights complement an existing network to most of these countries with regular flights scheduled to Krakow and Warsaw in Poland and Bucharest in Romania.
BA will also start a new summer service to Perugia in Italy on June 28, delayed from 2020 due to the impact of the pandemic.
BA network and alliances director Neil Chernoff 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 the carrier’s short-haul Airbus fleet.
