There are many myths about the best time to book a flight in order to get the cheapest deals. While booking flights cheaper to the date can be risky because the flight prices can actually go up, sometimes there is a sweet spot between booking too far in advance and booking too close to your travel dates. The ideal time to book will depend on the location you are traveling to, the demand at that given time, and whether there are low-cost airlines traveling the route you want to take, as low-cost airlines tend to have more volatile pricing structures.
