Yes, you still go through security when flying on a private jet, but the experience is radically different from the standard TSA process at a commercial terminal. Instead of waiting in long lines at the main airport, private passengers typically use a Fixed-Base Operator (FBO), which is a private terminal building. Security procedures are managed by the charter operator or the FBO staff and are governed by the TSA's "Twelve-Five" or "Private Charter Standard Security Programs." While you won't always have to remove your shoes or liquids, your identification is strictly verified against the passenger manifest, and your luggage is often screened using X-ray machines or explosive trace detection. For international private flights, you must still clear Customs and Immigration, though this often happens directly on the tarmac or inside the FBO lounge with a dedicated officer. The focus is on ensuring no prohibited items (like weapons or explosives) board the aircraft, but the process is designed to be discreet, fast, and respectful of your privacy.
