Newark was the first major airport serving New York City and is the fifth busiest international air gateway to the United States. Amelia Earhart dedicated the Newark Airport Administration Building in 1935, which was North America's first commercial airline terminal. In 2003, Newark became the terminus of the world's longest non-stop scheduled airline route, Continental's service to Hong Kong. In 2004, Singapore Airlines broke Continental's record by starting direct 18-hour flights from Newark to Singapore. The airport is located in Newark, New Jersey, about west of downtown Manhattan.
