Finnair has launched up to four weekly flights to Istanbul as part of its winter schedule.
Changes came into effect on Sunday (October 25th), meaning that flights to Turkey's largest city will be operated during the winter months by the airline for the first time.
To accommodate the route, Finnair has removed flights to Rome from its winter schedule.
Elsewhere, the carrier will launch three weekly flights to Phuket using its own Airbus aircraft, while flights to Bangkok will be increased to two a day.
Petteri Kostermaa, Finnair's vice president of route strategy and traffic planning, said: "The two daily flights on the Bangkok route, which is particularly important for Finns, reflect the popularity of Thailand tourism."
The airline is also introducing a fifth weekly flight to Tokyo after experiencing increased demand for the route.
In a further change to its schedule, Finnair has stopped its flights to Stuttgart over the winter.
From November 24th, the carrier will switch from Terminal 2 to Terminal 5 at Stockholm's Arlanda Airport.
