Key Details on Physical Body Checks

• United States: The TSA extensively uses millimeter-wave body scanners. If the scanner flags a spot or you opt out, a mandatory, thorough pat-down of the body is required.
• Israel: Known for intense, intelligence-based security. Pat-downs can be part of extensive, multi-layered screening for flights, including personal interviews and, in rare cases, more invasive searches.
• European Union & UK: Many airports use body scanners; if a scanner alarms or you opt out, staff will conduct a pat-down to ensure safety.
• Australia & New Zealand: Body scanners are common. Security personnel will conduct a pat-down if the scanner detects an object (metallic or non-metallic) or triggers an alert.
• Other Regions: Canada and various Asian/Middle Eastern hubs (like Singapore, Hong Kong, and Thailand) use a mix of technology and manual checks, where a pat-down is a standard contingency.
