Received a New York Times news alert a few minutes ago detailing changes to screening procedures. Long story short, if you are a citizen of traveling from our through certain countries suspected to be sponsors of terrorism, you can expect a full pat down and bag search before you board a flight to the United States. However, if you are an American Citizen, you will no longer be automatically subjected to a pat down (and whatever else they were throwing at us) before boarding a flight heading to the US from other countries. But don’t be surprised if you are randomly subjected to extra scrutiny. You can review the New York Times article here for more details. Here is TSA’s press release on the change.
I doubt very many people realize it, but citizens of certain countries have been subject to extra security for about as long as I can remember, even pre-dating 9/11.
