At first blush, Korea has much to celebrate. Flagship airport Seoul Incheon International saw a 9.7% increase in 2014 passenger numbers, well above the country's 3% GDP growth rate. Visitor arrivals increased 17%, continuing a streak of near double digit annual growth. These are accomplishments, but Seoul Incheon is worried about falling transit traffic: after over a decade of transit growth, 2014 saw a half million decrease in transit passengers. The share of transit passengers fell to 16% from a high of 18% in 2009.
