Yours words today were smuggle, seat and melt.
If you go through TSA at any US airport you will be asked to remove way too many clothing items and throw away much too much in the way of beauty products and lotions. That is unless you get TSA precheck. Then you go through with virtually no change but your bag on the belt. Precheck requires an FBI background check, so if you don’t mind Big Brother invading one more personal space, it is so worth it if you are a frequent traveler. My one piece of advice – Do not try to smuggle a chocolate bar onto the plane, in your pocket, because the minute you sit in your seat it will melt and become a hideous brown stain on the back of your pants. At that point, no one will believe that you like chocolate that much!
