Someone coined a term for (over-) planned hub-cities like Incheon: "aerotropolis":
Today, the ubiquity of jet travel, round-the-clock workdays, overnight shipping, and global business networks has turned the pattern inside out. Soon the airport will be at the center and the city will be built around it, the better to keep workers, suppliers, executives and goods in touch with the global market. This is the aerotropolis: a combination of giant airport, planned city, shipping facility and business hub. (source)
