Flying in South America

Today, on this date in 2015. In Bolivia. Took the flight from Santa Cruz to sucre, Bolivia. This is really an old plane. 18 years old. A plane the same as this crashed one week later, carrying a team of footballers. Really uncomfortable as i was always flying on brand new dreamliners or Airbus prior to this. When you are in South America, the distance between each city is really far. When I was in Argentina, I took more than 30 hours of bus ride, non stop, from one city to another. And it is not cheap too, 400 usd each.
