British Airways will launch a four-times weekly service between Heathrow and Krakow in May 2015.
The direct route will be operated by Airbus A319 and A320 aircraft in two-class configurations with Club Europe business and economy cabins.
BA will fly from Heathrow’s Terminal 5 to Krakow on Mondays, Wednesdays, Fridays and Sundays, from May 1, 2015, although flight times will vary on different days.
The service to Krakow will be BA’s second Polish route as it already operates a double-daily service from Heathrow’s Terminal 3 to Warsaw.
Neil Cottrell, BA's head of planning, said: “We have a long history of flying to Poland and opening a route to the country's second city now offers far greater choice for customers.
“With a sizeable Polish community in London, we know the route will be popular with Poles visiting friends and relatives. It will also serve our business travellers well as Krakow is an important economic hub which has seen significant UK investment and trade.”
