Request For Airplane Ticket Price Datasets

I’m a student in college and am attempting creating a flight price predictor with machine learning algorithms.

But I have currently faced issues at finding datasets for airfare prices which include travel destinations, dates, prices, airlines and countries preferably international.

Most datasets are behind a pay wall and there are no updated tutorials which work such that I can use web scraping to get those data.

So could you guys help me with finding those resources. Thank you.
