Here is some information about Sydney Airport:
Sydney Airport, also known as Kingsford Smith Airport (IATA code SYD), is located in the Sydney suburb of Mascot. It is the major airport serving Sydney, and is a major hub for Qantas. Sydney Airport is one of the oldest continually operated airports in the world, and the busiest airport in Australia, handling 31.9 million passengers and 290,346 aircraft movements in 2007.
Originally declared an aerodrome in 1920 (then known as Sydney Airport), it was renamed Sydney (Kingsford Smith) Airport in 1953, in honour of Charles Kingsford Smith, a pioneering Australian aviator.
The airport's first runways were built in 1933, all in gravel. Some small streams where some of the present runways are located were also filled. By the 1960s the need for a new international terminal had become apparent, and work commenced in late 1966. The new terminal was officially opened on May 3, 1970, by Queen Elizabeth II. The first Boeing 747 'Jumbo Jet' to serve the airport, Pan American's 'Clipper Flying Cloud' (N734PA), arrived on October 4, 1970. In the 1970s the north-south runway was expanded to become one of the longest runways in the southern hemisphere. The international terminal was expanded in 1992 and has undergone several refurbishments since then.
Sydney Airport has three passenger terminals. The international terminal is separated from the other terminals by a runway, therefore passengers need to allow for longer times for transfers. The airport does provide shuttle services between terminals.
