Like other airline applications, Fly Delta allows you to book and manage flights up to, and including generating boarding passes on the smartphone. You can tie your frequent flyer miles account and other Delta services to the app.
With Android Wear integration however, now when you check-in on your flight, your boarding pass and itinerary get pushed to your watch. That will come in handy as you can keep your phone in your pocket or holster when it is time to board the aircraft.
Other updates to the Fly Delta app include some bug fixes, the ability to remove trips that are not part of your SkyMiles frequent flyer account, and a revised overall user interface. If you happen to use Delta (if you live in Atlanta, Georgia, you probably do), and have a new Android Wear smartwatch on order, app support is on the move.
