As a flight attendant I am asked frequently what is permissible and not permissible do to at an airport. This article covers the basics on what not do to at TSA so your brief interaction with them is smoothly and quickly. Just follow the rules, be polite, and watch out for others is what I would add to this article:https://www.smartertravel.com/airport-security-tips/?source=91&u=C721687801&nltv=&nl_cs=53564312%3A%3A%3A%3A%3A%3A&e_send_id=967db1a6-698f-40c9-a1d2-1c6592ef84e9&emd5=09cc896557dfc2e4e6c9315942f7ce93&esha256=7cf86399c707a48208643add7c96400525499d29baad829b267b03bee643b2e7
TSA Precheck is a lifesaver and a great investment, especially to those who travel frequently.
Happy and safe flying, everyone!
