I finally (turned my head and) coughed up the extra money for TSA precheck. The biggest benefit is that the other people who are in that line HAVE ACTUALLY FLOWN IN THE LAST YEAR AND KNOW THE ROUTINE. I got tired of getting hung up by the people arguing with TSA over liquids and amounts - Yes, you probably are right that you can bring a gallon of breastmilk or baby formula on the plane but TSA don't know that and TSA don't care. And empty your pockets into your bag before you get to the line Mr. keys and change and pen and chapsticck and wallet amd handkerchief and notepad and passport and phone and gum and lighter and cigarrettes and receipts and random piece of string. HERE ENDETH THE RANT.
