Did you know that the TSA keeps items left behind at security checkpoints for a minimum of 30 days and posts phone numbers on its website (https://www.tsa.gov/contact/lost-and-found ) where travelers can contact the lost and found departments at each airport? Keep in mind that airports and airlines will have their own lost and found procedures for things left in the terminals and on airplanes. To help get your stuff back, we suggest you tape a business card to your laptop and smartphone. Also while standing in line, take time to consolidate all of your small items and pocket items and bring an extra plastic bag to stow them in your carry-on just for the scan. We look forward to the introduction of advanced 3D X-ray scanners that will allow us to keep our electronics in our carry-ons. Hopefully this year?  And what about those liquids and gels that that don’t meet the TSA code? If you can’t get the items into a checked bag, look out for Airport Mailers (now in 22 US airports) and similar companies to pay to have them mailed home.
