If you'd like to have some extra spending money on your Castelo de Paiva holiday, then listen up! As any experienced jet-setter knows, don't book at the very last minute. Prices are often highest just prior to the departure date. Another easy way to pick up a bargain is to compare all options. If your destination has several airports, don't forget to look into the cost of flying into a smaller terminal. Last but not least, be prepared to book quickly if you find a great price. It might not stick around for long! With a bit of knowledge and some luck, the perfect fare can be yours.
