Pair this with the CLEAR trusted traveller program, which seems very smugly in bed with the TSA, and you can see how this is a direct strike of the government against the airline's elite security line arrangement to a single government sanctioned program (i.e. CLEAR).
I guess I'll add another half hour to the time I'm going to be spending trying to clear Terminal A security which is just wonderful when you combine it with the closure of the main terminal CRC.
