Turkish Airlines’ low cost subsidiary AJet is discontinuing its flights between Istanbul Sabiha Gocken Airport and Tuzla after a year and a half of operations. The last service on the route, which was maintained on a weekly basis, will run on June 1. Pegasus Airlines continues to link the two airports with a one weekly flight. It has scheduled the 239-seat Airbus A321 aircraft on the route for most of the upcoming peak summer season.
