Last year, TSA officers screened a record-breaking 3 million passengers, and their luggage, in a single day. If that sounds like fun, I have good news: They’re hiring. If you want to help TSA, but not work for TSA, I also have good news. I recently asked a TSA agent, Uniformed Advisor TeaNeisha Barker, what passengers can do to make her job easier (as a travel writer who spends more time in airports than at home, I know that happy agents equal happy travelers).
