Secure our Skies Act of 2017 This bill requires each air carrier providing passenger air transportation to provide flight attendants, pilots, and dispatchers who are employees or contractors of the carrier with training to combat human trafficking in the course of carrying out their duties. Such training shall cover: (1) common indicators of human trafficking, and (2) best practices for reporting suspected trafficking to law enforcement officers. To assist in such training, the Department of Homeland Security and the Department of Transportation shall provide information, including the Blue Campaign training module, for use by air carriers. The Federal Aviation Administration shall report recommendations for improving the identification and reporting of human trafficking by air carrier personnel while protecting the civil liberties of passengers. The bill grants immunity to an air carrier for reporting any suspicious transaction relevant to a possible violation of law or regulation relating to human trafficking.
