I've flown in out of Ben Gurion on several occasions. The lines are long and move slowly. If you tried to do that at a large metro aiport, you would need to arrive perhaps 6 to 8 hours before the flight. (Just my opinion on the time)
TSA has never stopped one terrorist and they won't until profiling becomes the norm. Sooner or later there will be another airborne attack and when it comes TSA will say they aren't tough enough and want to up the stakes once again.
What is occurring now in airports is tyranny and a violation of the 4th amendment and is completely unnecessary.
