I don't but I'm thinking about visiting BOG and this puts me off completely. I have seen a documentary by CBC a while back stating that IST is the main transfer hub to South America (to get to either the US/Canada). As a non-white person with legitimate reason to visit a country I don't want to be treated as one of them. After seeing that documentary I started to understand why I was not treated nicely at IST when I was travelling alone.

Many years back, when we arrive at CPH on TK flights, we were told to have our passports ready as the police were ready to do passport checks by the gate. I tried that with Thai arriving CPH too (many years back). I haven't seen that for the past 5 years or so.
