In the coming weeks, the Google Assistant will proactively notify you by phone if it predicts a flight delay and “we’ll tell you the reason if we know,” the company added.
Using flight status data combined with Machine Learning (ML), the Google Assistant will soon let you know over the phone if your flight is delayed even before the airline announces it.
According to Google, the digital assistant will notify users via phone when its algorithms predict that their flights will be delayed.

Earlier this year, we started sharing flight delay predictions (via Google Flights) when you search for your flight status, and we're 85% confident that if we say a flight will be delayed, it will be.
"We use historical flight status data combined with machine learning to make these predictions before airlines confirm delays," Google said in a blog late Tuesday.
"You can ask something like 'Hey Google, my flight is delayed' or 'Hey Google, what time is my flight expected to arrive at Eleftherios Venizelos Airport?'" the company said.
