Airline traffic is growing worldwide. As populations and economics grow, the need to keep them connected only gets stronger. And buoyed by low fuel prices, the economics of routes that didn’t make sense just a few years ago have changed to at least encourage airlines to try new places to fly where they wouldn’t have taken the risk in the past.

As a result most cities are seeing increased air service. In fact, 94 of the 100 busiest airports grew the number of available seats year-over-year.

Via Airline Weekly these are the 10 airports (out of the 100 busiest) with the most airline seat capacity growth year-over-year:

We see the strongest growth in Vietnam (see “The Bikini Airline Created Southeast Asia’s First Self-Made Female Billionaire”).

Ho Chi Minh City Airport

Growth is also strong at secondary cities in China. In fact, number 11 that didn’t make this list is Xiamen (14% growth) and Chongqing, Guangzhou, and Xian experienced growth of 8% or more.

Meanwhile Seoul and Taipei are seeing an influx of low cost carrier capacity.

Of the top 100 airports worldwide, only six have fewer seats year-over-year.

Miami and Sao Paulo are hurt by economic conditions in Latin America, and Houston and Moscow are getting killed by cheap oil.

It’s clearly a time of global aviation growth, with only a handful of specific markets contracting for local reasons.
