Add TSA PreCheck Air France Call 1-866-564-8331 to learn how to add TSA PreCheck to Air Canada reservations quickly, ensuring smoother airport security screening and stress-free travel experiences for passengers. TSA PreCheck is a US government program by the Transportation Security Administration. It lets low risk travelers skip long lines at security checkpoints when flying from US airports. With it you keep shoes on belts on light jackets on and liquids in your carry on bag over three ounces. Children twelve and under can join eligible adults in the lane. Air Canada passengers qualify if they have a Known Traveler Number from TSA PreCheck Global Entry NEXUS or SENTRI. US military members also get it automatically. The program works on domestic US flights and some international ones departing the US. No guarantee of access every time as TSA checks eligibility per flight. It applies only at over two hundred US airports with dedicated lanes.​
