Turkish Airlines will add two extra weekly services onto its Istanbul to Birmingham route next summer.
From March 29, the carrier will operate 12 flights per week between the two cities.
Selim Ozturk, the airline's general manager at Birmingham airport, said: "Outside of London, Birmingham is the UK's third largest airport, handling more than 9.5 million passengers a year and serving 140 direct destinations worldwide...
"The new flights will provide additional domestic and international connections to our passengers travelling from Birmingham."
Last week, Turkish Airlines announced it will increase its Istanbul to Manchester services in summer 2015 (see news, December 16).
