The good news I hear is that if you are traveling on a major US carrier, their systems are still intact. Download your tickets to your phones and store them in the Wallet (iPhone) or a screen shot (Android). No WIFI at the airport. Hopefully you are on Alaska or Delta and at worst your bags will be slightly delayed. Take all medication WITH YOU in a carry on. Good luck!
Sounds like this guy needs a lesson in communication, whats wrong with the control system? Also this business seems to be going the wrong way, carry on baggage is the problem with boarding and exiting the aircraft. Maybe the airlines need to revert to using their own computer systems to minimize risk.
