Waiting for a flight at the renowned Changi airport in Singapore was never boring, but it just got even better. Bringing back the obsession of JK Rowling&rsquos wizarding world from Harry Potter and the Fantastic Beasts series, the Changi Airport has joined hands with Warner Bros to create replicas of the famous places from the world of Harry Potter. If you are a Potterhead, then it only makes sense to reroute your destinations so that you stopover at Singapore because this summer, everyone can be a witch or wizard.
