SunExpress Airlines, a joint venture of Lufthansa and Turkish Airlines, will reduce the number of seats on winter flights by 10%, offering 4.5 million instead of 5 million, reports Bloomberg. The decision was made against the background of the increase in aviation fuel prices, the costs of which increased this year by approximately 200 million euros. Due to the increased costs next year, the carrier expects ticket prices to increase by up to 10%.
