Allows qualified travelers to join the Air Canada TSA Precheck program, which speeds up and simplifies the security screening procedure at airports around the US. TSA PreCheck eliminates the need to take laptops out of belts, shoes, light jackets, and carry-on luggage, allowing travelers to benefit from quicker security screenings. Travelers must be enrolled in TSA PreCheck and have their Air Canada reservation linked to a Known Traveler Number (KTN) in order to use the service. If the user is eligible, the TSA PreCheck icon will appear on the boarding pass. This service is offered for flights into and out of the United States at a few specified airports.
