If you'd like to save some cash on your Double Bay holiday, listen up! As every experienced traveller knows, don't leave booking until the last minute. Fares are generally more expensive close to the departure date. Also, look around online and compare your options. If your destination has several airports, you may be able to score a better deal by flying into one that's further away. Last but not least, another easy way to save a few dollars is be ready to book fast. If you stumble on a good deal, don't hold off — snap it up while the opportunity's there.
