Flight delay alerts are helpful only when airlines notify you on time. But they are not always accurate. To fill that gap, Google is using AI to help predict potential flight delays. As this feature is part of the Google Flights app, it will make the historic flight status data fed into a machine learning algorithm to predict delays.
Whether the delay actually happens or not, the Google claims the predictions to be 80% correct. As an air traveler, you still have to show up on time at the airport, not to miss a flight due to pessimism. The feature is useful for those who tend to be economical. Check out for the details about this feature and may be able to avoid horrible flight delay surprises.
