I stopped listening to TSA PR bs a long time ago, it attempts to obscure what is really happening moe often than not. TSA has never liked premium lines, no idea of how MKE operates, but most places aren't overly thrilled to have TSA throwing their weight around as has been happening for quite awhile. At IAD for example, the airport/lines were under pressure to remove the priority screening line b/c look, we can take care of that for you
. (note, I focused on the existence of the black diamond, not their other line designations - the family line separation was the anxiety reducer option and that can work for them as it separates them into a "slow" area)
ps no reason to bold everything you quote
