Sydney Airport (SYD)

The Sydney Airport, or also known as Kingston Smith Airport, is one of the oldest airports in the world. Flights at a grass field close to Sydney started in the 1920s. Since then three runways have been build and the airport developed into one of Australia's busiest with close to 40 million passengers.
The close proximity to the city and the layout of the runways is causing a lot of noise complaints. Flights in the nighttime are prohibited and there is a maximum of flights per hour. This inflexibility can cause long delays during peak hours as there is no possibility to 'catch up'. Plans were made to build a new airport but those were shelved recently, keeping the airport at its present location for at least a decade.
