You have to look beyond the direct costs to the costs imposed on travellers and how their reaction impacts the airlines. TSA's current model is expensive for the airlines because it is deterring people from flying. It's expensive for airline travelers because it's adding significantly to the hassle of flying: I believe that many flyers would pay more for the Israeli model if it was at least equally effective because it saves time. I believe that they would pay even more if it was not only less hassle but more effective than the current "security theatre" approach.
