To get through el al security they ask you a zillion questions, they look you up and down and if you act just a bit nervous they interrogate you..I went to Israel last year through LAX you don’t mess with el al security they are top notch
Flying into Moscow in the mid 1980's was like that too. You go into a glass booth with mirrors behind you, the guy looks you up/down all over, makes a few calls, taps on the computer, asks more questions, and eventually lets you in.
If you fly out of DFW and have metal in your joints they will grope you rather than interrogate. Thanks, I’ll take El Al.
