The goal of this project is to find the best time to buy an airline ticket. Airline ticket prices vary depending on how soon the flight is. Using attributes of a specific flight, the team will try to predict the optimal date to purchase a ticket. For instance, it is generally true that the farther in advance you buy a ticket the cheaper it will be. However, this is a very simple heuristic which may not be true. In this project, the team will be in charge with determining  the relationship between flight date and flight cost. Additionally, the team will build a predictive model so that a user can choose a specific flight and be given an optimal date to purchase the ticket.
