Yes, private jet passengers must go through security screening, but the process is significantly more streamlined and private than the commercial experience. Instead of the main terminal, private flyers use a Fixed Base Operator (FBO), which is a private terminal building. Security checks here are typically conducted by specialized staff or the flight crew and often involve a quick identity verification and a non-invasive luggage scan. In many cases, you can arrive just 15 minutes before departure and walk directly through the FBO to your aircraft. However, for international flights, you must still clear customs and immigration, which is often handled by a dedicated officer at the FBO or sometimes even on the plane itself. While you skip the long TSA lines and the "shoes-off" ritual of the main terminal, the legal requirement for security and manifest checks remains mandatory to comply with aviation safety laws and international border regulations. The focus in private aviation is on high-security standards delivered with maximum discretion and speed rather than the mass-screening approach used for the general public.
