If you want to have some extra spending money on your trip to Gaoshu, then listen up! As every seasoned traveller will tell you, don't book at the very last minute. Airfares are usually more expensive just prior to the departure date. Also, shop around and compare your options. If your destination has more than one airport, you may be able to pick up a fantastic price by flying into one that's further away. Finally, another easy way to save some cash is be ready to book fast. If you come across a fantastic bargain, don't hesitate — snap it up while the opportunity's there.
