Air Canada is a participant in the TSA PreCheck program, which allows qualified travelers to get faster security screening at American airports. Air Canada TSA PreCheck travelers can get through security checks faster if they continue to wear shoes, belts, and light coats and leave laptops and liquids in their bags. To use TSA PreCheck with Air Canada, your frequent flyer profile or reservation must have your Known Traveler Number (KTN). TSA PreCheck is available at US airports only; airports in Canada are not eligible for this program. This service is ideal for frequent passengers who want a more seamless airport experience.
