Few sectors will benefit as much from globalization and economic development as air travel. People in emerging economies typically can’t afford to fly much, but as their income rises (the x-axis), so does their number of airplane trips per capita (the y-axis). Note the inflection point when income passes the US$20,000 mark. As tens of millions of people in populous nations such as China and India move into the middle class, the skies will become a lot more crowded.
