How does the Flighty app predict flight delays?

Answer: With machine learning.

Planes on the tarmac of an airport with the sun rising on the horizon.
Flight delays happen all the time, but airlines are often stingy on details when telling customers about them. That’s why many have turned to Flighty, an app that tells you all the details behind your delayed flight. The newest version of Flighty, released Tuesday, uses machine learning to inform you of a delay long before the airlines will.

Flighty 4.0 tracks and analyzes a host of factors that could impact departure times, such as late planes, air traffic control notices, weather forecasts and airport operational issues. It then uses this data to give you an upfront estimate of how long your flight will likely be delayed as soon as an issue arises. For example, Flighty 4.0 can predict delays due to late-arriving aircraft up to six hours before airlines will acknowledge them. The company behind Flighty reports that its predictions are more than 95 percent accurate.

You’ll have to pay up for those advanced predictions, though. These new features are only available with a Flighty Pro subscription for $4 for one week or $48 for one year.
