What is a TSA pat-down and can I opt out of the body scanner?

The short answer

Yes, most passengers can decline the TSA body scanner (AIT) and have physical screening instead. The exception is a small number of passengers whose boarding pass shows they were selected for enhanced screening, who must go through the scanner. You can ask for private screening at any time.

Can I opt out of the TSA body scanner?

TSA's screening information says passengers generally have the opportunity to decline AIT screening in favor of physical screening. Some passengers must undergo AIT if their boarding pass shows they were selected for enhanced screening, which TSA describes as a very limited number of cases.

TSA says AIT uses millimeter wave technology, not X-ray, and shows a generic outline with flagged areas rather than a passenger-specific image. Its FAQ confirms that if you decline both AIT and a walk-through metal detector, you will undergo a pat-down. The pages we read do not say whether you can refuse screening entirely.

What happens in a TSA pat-down?

TSA says you may get a pat-down if screening technology alarms, as part of enhanced screening, or as an alternative to AIT. TSA PreCheck passengers may also receive one.

An officer explains each step beforehand, and you are patted down by an officer of the same sex.

• It may include the head, neck, arms, torso, legs and feet, as well as sensitive areas
• Officers use the back of the hand over sensitive areas, and may use the front of the hand in limited cases
• You may be asked to adjust clothing
• Tell the officer if you have trouble raising your arms or holding a position, have an external medical device, or have areas that are painful to touch
• You can ask for a chair

Can I ask for private screening?

Yes. TSA says you can request private screening at any time during the screening process, and you may bring a companion of your choice as a witness. A second officer of the same sex will always be present during private screening.

What clothing do I need to remove before the scanner?

TSA says light outer garments, such as windbreakers, blazers and vests with full front zippers, and bulky clothing, such as oversized hoodies and cardigans, must be removed before AIT. If you cannot or will not remove them, tell the officer, because additional screening may follow.
