Although my quart-size Ziploc bag holding containers sized 3 ounces or smaller has slid through airport security unquestioned everywhere from LAX to LGA, Miami, Montego Bay, Moscow, Newark, JFK, and Nice within the past few months, when I put it through the X-Ray machine at PBI yesterday, the TSA worker stopped me. "Why have you got so much stuff in here?" she asked. Now, when a TSA worker asks a dumb question, you can't risk sounding impertinent by saying something like, "TSA rules say there's no limit to the number of containers you put in your quart-size Ziploc bag, as long as they're each 3 ounces or smaller." So instead I pointed to my kids and said, "That stuff is for three people." The TSA worker let me through . . . after throwing out the few mouthfuls of water in my 3-year-old's sippy cup.
