The Greek island of Kos is to be added to British Airways network from Gatwick next summer.
Flights will run three days a week on Tuesdays, Wednesdays and Saturdays from May 15 until October 26, 2019.
Fares start at £70 one-way in economy and £222 in business class.
BA currently serves 11 destinations in Greece – Athens, Santorini, Rhodes, Skiathos, Thessaloniki, Zante, Mykonos, Kefalonia, Kalamata, Crete and Corfu.
The Kos flights will be served by a mixture of Airbus A319 and A320 aircraft from Gatwick’s South Terminal.
The airline is also increasing the number of flights from Gatwick to city break destinations this winter, including Palma, Turin, Geneva, Lanzarote and Malaga. A new air link to Cologne takes off from November 16.
BA Gatwick managing director, Adam Carson, said: “Greece is incredibly popular with our customers, so we’re excited to add another sunshine route to our growing network, giving holidaymakers even more choice of destinations at competitively low prices.
“From Gatwick we fly to more than 50 short-haul destinations and 70 long-haul and our wider network continues to expand as we add in new routes designed to appeal to both leisure and business customers.”
