Understanding Passbook

Keeping all of your passes/tickets in one place. For instance, a boarding pass, a movie ticket and your starbucks card. You download the individual apps, then get your passes sent to passbook. Keeps them all one in place for easy use.

 

I used it for an American flight a few months ago and it worked flawlessly.

Like the guy above said, it consolidates all of your gift cards, boarding passes, and tickets into one place. It also pops up on the lockscreen to give you a reminder.

 

You'll use airline app to control and configure your account, purchase tickets, etc.

Onec you have a ticket through American Airlines, if you are flying out of a Terminal that supports Passbook. It can send your ticket to Passbook, and Passbook is location aware. While you are in airport, your boarding pass will be available from lockscreen.

Very convenient, and paperless.

 

You can pull up your ticket from the United app as well, but Passbook just adds a convenience factor to it. Example, use the app to check fro flights, book them, and view your digital boarding pass. Then add it to Passbook.

When it's in Passbook, it will update you if there is a gate change, flight delay, or cancellation. Then, when it comes time to board, it's right there on your lock screen.
