Abstract: Machine Learning is a part of Artificial Intelligence. In Machine Learning, there are many algorithms exist. In this project usually I used Linear Regression to predict the Air Flight Price. Even though we have many apps in line through them we also can check the price but the difference between this app and my model is this price is select or modified by the author of the particular airlines but my model can predict the price without any modifications. There is no option that depends on humans. If humans want to change the price of any special day, they can't do it. Because every price and prediction depends on the machine.
