How can I design Airports?

Most airport terminals are built in a plain style. However, some, such as Baghdad International Airport, are monumental in stature, while others are considered architectural masterpieces, such as Terminal 1 at Charles de Gaulle airport near Paris or Terminal 5 at New York's JFK Airport. A few are designed to reflect the culture of a particular area, an example being the terminal at Albuquerque International Sunport in New Mexico, which is designed in the Pueblo revival style popularized by architect John Gaw Meem.
