Otherwise you could just visit the Delta application and leave the application while viewing your boarding pass.

Thats how it worked before and essentially thats how it works today.

Without the show on lock screen and automatic updates, integrating with Passbook is pretty worthless.

I just can't believe when Passbook was announced Delta was chosen as a partner. Then it took them about 6 months to release the new application to find out that the application is actually even slower than before and they didn't even execute Passbook correctly. They missed out on the features people were actually excited about during the presentation.

"and it integrates with the lock screen"

I don't even think it would take much to pass the variable of show on lock screen. That should be pretty standard. Automatic updates may be a bit trickier, but this is a huge miss on execution from Delta.
