Latin America has long underperformed in aviation business terms, as airlines and associated industries deal with under-developed infrastructure, varying regional regulations, a lack of investment and a fragmented airspace system. Latin America has a population of more than 600 million people, with 95 scheduled carriers operating more than 1,000 commercial aircraft. The region was responsible for approximately 6.2% of world traffic in 2009, while holding more than 9% of its population. Air transport in Latin America is forecast to be among the fastest growing in the world over the next 20 years.
