A step towards iTravel? Delta and American Airlines confirm support for Apple Passbook

Skift Take
It looks like Apple Passbook in iOS 6 will get some big traction from airlines for mobile boarding passes. If Apple goes ahead eventually with a full-fledged iTravel offering, then that could be a different story entirely.
With Apple expected to unleash iOS 6 next week, you can expect Delta Air Lines, American Airlines and undoubtedly other carriers to be supporting Passbook's mobile boarding pass functionality at launch or soon thereafter.
With Passbook, you'd be able to scan your iPhone or iPod as mobile boarding passes at airport gates for airlines that support the feature. Passbook would even automatically display the boarding pass when you arrive at the airport.
