Google introduced Flight Status Feature

Google introduced a new feature called flight status. Now you can check the status of the flight online with the help of google. You can avoid the flight delay. Rather than waiting as airport for flight, you can spend more time with your family at your home.

For the latest information on a flight's status, simply search for an airline and flight number, and the first result will tell you whether your flight is on time or delayed as well as the estimated departure and arrival times. Here's a quick example for a specific American Airlines flight:

 
Hopefully this makes your travels a little smoother.
