South Korea and Turkey have expanded their bilateral air services agreement.
The new deal immediately raises the number of frequencies between the two countries from seven to nine. It will then be increased to 11 times weekly from March 2014, says South Korea's ministry of land, infrastructure and transport.
Innovata schedules show that Turkish Airlines operates a daily Istanbul-Seoul Incheon service. Asiana Airlines and Korean Air also operates three and four weekly services on the route respectively.
