Earlier quoted context omitted.
As someone who flies through istanbul once a year, i was always surprised by the fact that there is very little security at us airports. :) I think it is more about penetration possibility more so than airport sevurity itself.
Security at US airports is hit-and-miss. Sometimes they check something and sometimes they dont. Rules appear to change daily and every checkpoint seems to interpret them slightly differently.
You get searched at the airport entrance, and get your luggage checked with xray scanners. Yoy get another one after passing the passport check done by cops. If you are flying to united states you get searched again at the gate.
On top of this, they verify your legal status at the checkin. It happened to me once when my greencard was approved but i only had the ead card. We literally spent an hour to get it sorted.
So i am not sure, but adding one more layer on top makes me feel sad.
Good thing turkish airlines will use specialized storage mechanism to store laptops in cabin. At least that will prevent things from getting stolen or potentially illegally searched.
