However, I have no guess as to the cost to each carrier to support Pre-Check (especially including IT changes).
I have no idea what percentage of BA, JL or CX's global traffic are passengers departing from US airports who are members of the Trusted Travelers programs (GE, NEXUS or TSA PreCheck).
That being said, this discussion belongs in the
No TSA PreCheck with Non-participating Airlines [merged threads] in the
Travel Safety/Security - Trusted Travelers forum (shameless plug for a forum that I co-moderate
).
