Air Canada is a participant in TSA PreCheck, which provides eligible passengers on flights to the United States with accelerated security screening. Air Canada TSA PreCheck passengers using TSA PreCheck can keep on belts, shoes, and lightweight coats while leaving liquids and laptops in their carry-on luggage. Make sure your booking or frequent flyer profile has your Known Traveler Number (KTN) updated in order to take advantage of this feature. Your boarding pass will bear the TSA PreCheck emblem if you qualify. Passengers on Air Canada traveling to the US can now enjoy a quicker and more convenient security experience at a few chosen Canadian airports thanks to this service.
