If you want to have some extra spending money on your trip to Guayanilla, listen up! As any seasoned traveller will tell you, avoid booking at the last minute. Airfares are often highest close to the departure date. Another excellent way to score the best price is to compare all options. If where you're headed has more than one airport, be sure to look into the cost of flying into a smaller terminal. Last but not least, another easy way to save some cash is be ready to book fast. If you spot an amazing bargain, don't hesitate — snap it up while you can.
