Incheon International airport is the latest symbol of South Korea’ s economic ambitions. The 5.6 billion dollar project includes a passenger terminal, which is the largest building in the country. The airport is part of a long-term strategy to place the country at the hub of South East Asia’s transportation and travel businesses. Economists are already forecasting that by 2025 Pacific Asia will have overtaken North America as the world’s busiest region for air passenger transport. The spectacular architecture of the airport buildings is just one of the attractions that it has to offer; equally important is the fact that the whole project has been located on what used to be part of the Pacific Ocean. As a result the airport is far enough away from residential areas to be able to operate twenty-four hours a day, without the burden of noise complaints from sleepless neighbors. Incheon is also ideally situated, lying midway between the capitals of two of the world’s major economies: China and Japan. Construction is scheduled to continue until at least 2020 with the addition of two new runways and a high-speed train connection to the capital Seoul, all of which will almost double the total cost. Incheon airport has certainly already made an impressive debut by winning two consecutive annual awards from the Airports Council International for the Best Airport Worldwide. The awards are based on more than 100,000 questionnaires completed by travelers at 66 international airports. Where is the airport located
