Yeah, Israel has been dealing with this for decades longer. Despite the fact that they are a much bigger target for terrorism than the United States (for obvious reasons), they actually have less of an incidence of airline hijackings and terrorism. Passengers are checked by people who really know what they're doing, and the cabins are sealed, pilots are trained in what to do.

The Israeli government has also made it very clear that it doesn't negotiate with terrorists; a threat to blow up a plane does not get a response.
