Is screening by imaging technology optional?

Generally, passengers undergoing screening will have the opportunity to decline AIT screening in favor of physical screening. However, some passengers will be required to undergo AIT screening if their boarding pass indicates that they have been selected for enhanced screening, in accordance with TSA regulations, prior to their arrival at the security checkpoint. This will occur in a very limited number of circumstances. The vast majority of passengers will not be affected.
