I used the new iOS Passbook app this AM to check in and check a bag at the airport. It worked great: I checked in for the flight with the United app yesterday, tapped the “send to Passbook” button, and that set me up for today.
To check my bag and pass through security I woke the phone and swiped the United notification, which was alerting me to my flight. I use a passcode on my phone, but Passbook bypassed that and simply displayed my boarding pass. I didn’t have to worry about locking orientation of the display, either. The boarding pass displays only one way, so it was easily picked up by the scanner.
United isn’t the only airline to link their iOS app to Passbook. It’s worth a try the next time you fly with your iPhone!
