British Airways is to start direct flights from Heathrow to Krakow in May 2015.
The new four times a week service from Terminal 5 will be operated by a combination of Airbus A319s and A320s.
BA already flies a double daily service to the Polish capital, Warsaw, from Terminal 3.
"With a sizeable Polish community in London, we know the (Krakow) route will be popular with Poles visiting friends and relatives,” said Neil Cottrell, BA head of planning.
“It will also serve our business travellers well as Krakow is an important economic hub which has seen significant UK investment and trade. We also expect the route to be very attractive to tourists who will be keen to explore this fascinating city."
From May 1, the four times a week service will operate on Mondays, Wednesdays, Fridays and Sundays.
Hand baggage only, return fares, with check-in baggage, starts from £104.
