The "kid" is 19. Just found out that the TSA said that they need "more" information in Phoenix than in other airports because of the "problems" they have at that airport, so the medicine bottles with his name on them were not sufficient. Someone at home found his driver's license and faxed that, but they want his birth certificate too. (???)
WN is being awesome on this and will get the kids on a flight once they clear security, at no extra charge. Kids mom is going to overnight his license to CA so he has it for the return trip.
