A 16-year-old passenger on our flight number TK35 to Montreal on 13 October 2017 got sick shortly after departure, as the health of our passengers is of the utmost importance we decided to return to Istanbul.
The aircraft is now holding and burning fuel until it reaches a safe landing weight. Our team has been informed that the last health condition of our passenger is very good. We will change our crew and prepare our aircraft again for a new flight to Montreal.
