I flew to Israel with a freind of mine, they gave him by mistake a wrong boarding pass with a different name, when we were about to board the plane he noticed the mistake, he went over the one of the TSA agents and told him what happened the TSA agent told him he should try to board the plain with the wrong BP he wants to see what will happen, when we were about to board the plain he showed his (wrong) boarding pass and his ID and the guy who checked/scanned it didn't say anything and let him go..
