an issue with some phones connecting to the passbook store when your phone is set to automatically update your time. If you disable automatic time in your iPhone time and date settings you will find that the passbook store will connect. Silly Apple. I was able to resolve the issue with Passbook not connecting to the store by unchecking AUTOMATIC UPDATE from Date and Time (Settings &gt; General) and resetting it manually to 1 year in advance. Close that, reopen Passbook, and it should work. Once it works, you can set the time back to update Automatically. When you get sent the flight reminder click on MOBILE checkin (not the web checkin) link - checkin and then it will say would you like to add it to passbook, and bam you have your boarding pass. It will be accessible from the lock screen on the day of departure. I have seen a couple of people attempt to use their passbook ticket in the US, however i do not think the infrastructure has been completely implemented just yet. I guess there is never any harm in trying though.... I've gotta say, I like the idea of being able to go onto the App Store and buy or download extension to Passbook. Perhaps Android needs to start doing that with it's Google Now system, so you can get cards appear when stuff happens.
