I am an Indian citizen. Recently I got a Schengen visa starting 20-03-18. I wanted to travel to Turkey, so I applied for a Turkey eVisa against the Schengen visa. My Turkey visa starting date is 10-03-2018 (ie 10 days earlier than the validity of the Schengen visa). I was not allowed to board the flight for Turkey on 10-03-2018.
Can I travel to Turkey on the same visa within the validity of my Schengen visa?
PS: My Turkey visa validity: 10-03-2018 to 05-10-18. Schengen visa validity: 20-03-2018 to 03-05-2018.
Now I am planning to leave for Athens on 22-03-2018 and enter Turkey on 29-03-2018 until 10-04-2018.
