Last year I had a flight get cancelled about an hour before it was supposed to start boarding. I got an alert from Flighty, immediately dashed over to the nearest gate agent, and got rebooked on another flight before American Airlines notified me that the original flight had been cancelled.

This happened to me last month while en route to the airport. I received a notification from Flighty that my flight was canceled. I trusted it and turned around. About 20 minutes later, the airline sent me the same notification. 🤷‍♂️

Flighty is truly a remarkable app and it pays for itself every time I fly.
