Sky Sports do Insure you as all the other Turkish Companies do. However, the insurance only covers Turkey So hospital treatment. If you are delayed by being in Hospital and need an Hotel you pay yourself. If you miss a scheduled flight you pay for a new flight yourself. If you need a medi-vac home, again it up to you and a medi-vac can cost from £35.000. Also any time you miss from your work, is not insured.
So, this is why you need to take out Hazardous Sport Insurance before you leave. This covers, Jeep Safaris, Kite Surfing, Paragliding and even Horse Riding.
Of course, the companies in Turkey tell you that you are insured, but have you ever asked what for??
