In 2006 my wife and I were interviewing for a position close to TYS. The interview went well, and all was good until we got to the airport and could not find my wife's wallet and/or ID/Driver's License. We thought we were totally hosed, but the woman at the counter (Continental Express) quickly informed us it wouldn't be a problem but we'd have to go through extra screening at TSA. She printed her a boarding pass with the dreaded 'SSSSSSS'. So - I took all of our carry-on stuff, and she went through by herself. The whole ordeal cost us an extra 5 minutes of time if you consider both the extra TSA screening as well as a brief explanation to the counter agent.
Today - a friend of mine posted on facebook that he lost his DL while traveling in PDX. He said that a friend overnighted his passport so he could travel tomorrow. I relayed my story back to him - but then got to wondering if this is common procedure or not.
So my question - what are the official rules and/or common practices for airlines if a traveler comes to the counter w/o propper ID and a sob story about losing it? Look forward to reading your responses!
