Direct flights between Singapore Changi and Darwin clock in at just under five hours, a common route serviced by carriers like Singapore Airlines and SilkAir. While the time difference is only an hour and a half, the airports themselves present very different operational models. A one-way flight from Darwin to Singapore can be found for around A$275 (with round trips as low as A$380), however, these prices, like the flight times, are just one part of a bigger picture.
