seems to have a daily flight from Istanbul Ataturk airport (IST)
(DEL) in 2012. They seem to fly the route with an
Airbus A330. The flight takes 5h 50min to cover the
distance of 4.513 km or 2.821 miles.
In October 2012 there is a bi-lateral agreement limiting the
number of flights to India to 7 a week.
Turkish Airlines uses both Indian and Turkish rights to serve
both Delhi and Mumbai daily.
As a result they have to codeshare with Air India.
But it seems that in 2013 Turkish airlines tries to obtain
doubble daily Delhi and Mumbai,
and on top five other destination in India.
