Enables eligible travelers to expedite and streamline the Air Canada TSA Precheck security screening process at airports around the United States by participating in the TSA PreCheck program. TSA PreCheck allows travelers to benefit from faster security checks by removing the need to remove laptops from carry-on bags, belts, light jackets, and shoes. To use TSA PreCheck, travelers must have their Air Canada reservation linked to a Known Traveler Number (KTN) and be enrolled in the program. The boarding pass will display the TSA PreCheck icon if the user qualifies. At select U.S. airports, this service is available for flights into and out of the country.
