Travelling by flight without parental consent?

If you're going with your grandparents there should be no problem with you going

I HATE planes tbh, but I remember when my Nanna used to live in Crete, I flew out every year on my own to go meet her.

I was always told that you can go anywhere, aslong as at the other end there's someone meeting you.
And Imo it's funner on your own because the Crew look after you really well, e.g sitting up front with them in the flight attendant seat, getting your food first etc.
And I got to freak out about flying without my mum worrying.

You will be fine! Turkish airline Onurair allow 14+ to fly unattended and I think most airlines are of a similar age. If your 17 you will have no issues.
