If you want to have some extra spending money on your trip to Voi, listen up! As every experienced traveller will tell you, don't leave booking until the last minute. Fares are often highest just prior to the departure date. Also, look around online and compare your options. If your destination has a few airports, you may be able to nab a fantastic deal by flying into a smaller terminal. Last but not least, another easy way to save some cash is be ready to book at a moment's notice. If you see a good bargain, don't think twice --- grab it while the opportunity's there.
