Can I get an airline employee when I'm about to board my flight?

You know that desk that you go to to check in or something and you give in your suitcases and label your carry-ons? Well can I get an airline employee to accompany me on my trip from Montreal-Istanbul, Turkey (direct flight)? I'm only 13 years old and I asked a previous question and someone said that human trafficking and prostitution was a big issue in Turkey so it wouldn't be a good idea to go alone. He also said that I would need to pay 100$ for the employee. Is this true?
