Last time I visited LA I went through an ocean of security processes.
1. Oslo Airport normal security. That's fine.
2. Heathrow Airport. Personal one on one interview. I must admire the skill of the interviewer. She talked to me like she had worked in my industry for 10 years and was extremely good at what she did. I felt interrogated though.
3. Heathrow by the Gate. Bomb Sweeping my suitcase.
4. LAX Airport Security on the way out.
Flying back to Norway, I was introduced to the face scanning by the gates. The scan felt intrusive and humiliating.
The rest of the flight was without any extra security, but having your face scanned feels really bad.
I have not really found a need to fly the US after this trip.
