At 18, Cristal Dyer left Australia on her first solo trip, venturing to South America where she volunteered for a year. Since then, she's become a full-time traveler. She shared her secrets to finding the cheapest flights and other travel deals with the Postcard Academy.    In this episode, you’ll learn how to find and take advantage of error fares (and what these mistake fares actually are); the best sites to find cheap airfare; where to book accommodation to rack up free nights; ideas to find local activities wherever you visit, and more. Cristal also shares some fantastic advice on what to look out for if you want to save money on traveling while giving back through global volunteering.    Links to everything we discussed can be found on postcardacademy.co   If you enjoyed this podcast, please subscribe and forward this episode to a friend.    You can follow Postcard Academy on Instagram, Twitter, and Facebook.    If you’re feeling especially kind, please leave a review on iTunes.
