How Do You Add TSA PreCheck® to Air Canada? Start by signing in to your Aeroplan account and adding your Known Traveler Number (KTN) to your profile. This will automatically apply TSA PreCheck® to future Air Canada flights. For an existing reservation, visit the Air Canada website, select “Manage Bookings,” and enter your KTN in the passenger information section. Ensure the name on your booking matches your TSA PreCheck® registration. Once saved, the TSA PreCheck® logo will appear on your boarding pass, giving you access to faster, more convenient airport security at eligible U.S. checkpoints when flying with Air Canada.
