Google Now is an extremely useful feature in Jelly Bean, and it has a new trick up its sleeve. If you check in online (with a supported airline) and a confirmation email is sent to your Gmail account, Google Now will show your boarding pass at the airport. It will have the barcode they need to scan and the terminal, gate, and seat for your convenience. As long as your phone is alive and connected to the internet, you’ll never need a paper boarding pass again! But just a suggestion: keep a paper boarding pass around anyway. Just in case. Google products, whether labelled or not, are generally all in beta stages.
