I push back against airlines in the US wanting to subject me to biometric boarding.
I push back against CBP questioning why I want out of biometric boarding/exit when flying out of my country.
In the same vein as the above, I will push back against TSA trying to subject me to CAT-2/biometric travel document checks.
I remain able and willing to miss flights in order to stand my ground within the rules — which is probably why it’s usually the rule-denying/misinformed screeners and border control types who end up frustrated with me at times and end up too eager to try to get me on my way so they can instead go get on other people’s cases. This CAT-2 thing is just another aspect of TSA TDCs that will probably play out for me in the same way as with CAT(-1), “requirements” for government-issued photo ID, and TSA’s name games at the TDC stations.
