Why am I not receiving the TSA PreCheck icon on my boarding pass?

There are several common reasons you may not see the PreCheck icon appear on your boarding pass. First, check to ensure your TSA PreCheck has not expired by looking up your Known Traveler Number (KTN)"Esto indica que el enlace lo lleva a un sitio externo que puede no tener las mismas políticas de accesibilidad o privacidad que Alaska Airlines. Al seleccionar el enlace de un socio, usted acepta compartir sus datos con estos sitios".. If you have an active PreCheck number, ensure the information associated with your KTN matches the information in your reservation (Full Name, Date of Birth, etc.). Lastly, it’s important to note that TSA PreCheck is not guaranteed every time you travel.
