If you'd like to have some extra spending money on your Batak holiday, listen up! As any experienced traveller will tell you, don't book at the very last minute. Airfares are usually highest just prior to the departure date. Another excellent way to land the best deal is to compare all options. If where you're headed has several airports, don't forget to look into the cost of flying into a smaller terminal. Last but not least, another simple way to save a few dollars is be ready to book fast. If you see an irresistible deal, don't hold off — snap it up while the opportunity's there.
