I apologize if this is mentioned in a separate thread dedicated to TSA Pre-Check. So, the assignment for Pre-Check on a particular flight is "random" since it's not guaranteed? Is that how it works for people who has TSA Pre-Check vs GE?
LAX
Access to Pre Check is
never guaranteed.
Anyone having a Known Traveler Number (members in various DHS Trusted Traveler Programs, TSA Pre Check, Global Entry, NEXUS, SENTRI) stands a very good chance of Pre Check selection
as long as the KTN is attached to the airline reservation.
But a "very good chance" is not a guarantee and should not be confused with a guarantee.
