When it comes to booking a holiday, there are two main questions you need to consider - (1) where the chuff am I going? and (2) how the chuff do I get there in the cheapest way possible.

Well while we can't specifically help on the former (other than point you to all the shiny videos/features/news on MTV Travel, that is), we're happy to report that Cheapflights have completed a truck-load of research (crunching over 10 billion lines of data, maths nerds) to help you understand when to buy and when to fly in 2017.

As a result, say hello to a Travel hack that could save you literally hundreds of pounds.

Not only that, but we're here to help break that data down. Introducing Cheapflights' 'Destination Diary' to help you plan where to go, and when for the best value in 2017.
