Some Airline Smart Phone Apps now allow you to have a "Mobile Boarding Pass" instead of having one printed out. Next week I have a trip coming up to the west coast and been thinking about giving the Mobile Boarding Pass a try through the Delta app. In the past I was a little concerned about encountering a TSA Agent who may not accept the Mobile version or worst case my smart phone dies from low battery or something before I get checked in. But it does seem like using the Mobile App could be a potential time saver.
I like to hear from other Insiders who may have used Mobile Boarding Passes and get their input. Have you encountered any problems? If there is more than one person in your party does each person need to have the app installed on their own phone?
