Flew in and out of Tel Aviv a couple of years ago. On the way out, I counted 11 checkpoints in one form or another that my wife and I passed through. It started on the road into the airport where our bus was pulled aside and two IDF soldiers came in with rifles and walked down the aisle eying every passenger, and we all were American tourists.
Once at the terminal, there are plainclothes security eying everyone entering. We were interviewed inside the terminal by a female security officer who asked us a lot of questions . We had to place our luggage on a conveyor. At the end, some people’s luggage was pulled aside for inspection with the passenger standing right there to answer any questions. From there, we continued to pass through other “inspection” stations, some obvious some not so obvious, including one last one as we were boarding our plane. There was a fellow in front of us who had purchased some lotions in the duty free store. The Israelis were quite apologetic when they confiscated them, explaining that bottled liquids were not of concern to Israeli security, only that US security does not allow such goods on flights to the US.
I have never felt safer in any airport, and the whole process was very efficient.
