SINGAPORE Airlines (SIA) and Turkish Airlines have mutually agreed to extend codeshare partnership to cover destinations beyond both Istanbul and Singapore.
SIA will also increase frequency on a seasonal basis between Singapore and Istanbul to six times weekly to meet demand growth demand on the route.
