Like most pilots, I also at times are outraged at how we are treated by security personnel and procedures.
However, flying as an SLF, on 21 December I cleared Customs and Immigration at KSTL (St. Louis Intl.). All personnel were very pleasant, and in the Christmas spirit.
I then had to process through a TSA security checkpoint. Without exception, all personnel were polite, friendly, professional, and also in the Christmas spirit.
On 3 January I departed KSMF (Sacramento) en route to Italy. Again, the TSA personnel were polite, friendly, and professional.
