It will probably suprise you as to how many are really scared of flying up there. I came short at a rather young age in Kinchsa so I have had my statistical "crash" and I actually like flying but 2 years ago on a trip to Buenos Aires with my family left me rather shaken and I cannot to this day tell you why. In the days running up to the flight I was suddenly having strange feelings of panic I could not explain - The trip out was rather a nightmare because I couldn't say anything because my mom is also afraid of flying. She flies but she is not happy about it. i normally sleep on a long flight even in Eco but this flight was different I was awake until hours into the trip until I was too tired to stay awake. The return trip on the other hand was no biggie.
I have flown several long distance trips since with no problem at all!!!
