How the Prediction Works

Our machine learning model analyzes historical flight prices between your selected airports. It uses features like the current ticket price, distance, and proximity to holidays to predict how many days before departure you should ideally book to get the cheapest deal.

It simulates purchasing the ticket on each possible day between today and your flight date, and picks the one with the lowest predicted price.

Technically, the model is a regression algorithm (e.g., Linear Regression and Random Forest Regression) trained on features like price, distance, days before departure, departure weekday, and holiday indicators. It predicts the expected ticket price for each possible purchase date, and selects the day with the lowest predicted value.
