Well, it was a News Report.
Basically, the airport is surrounded with ARMED Guards.
ALL carry on Items are compltely inspected. IE, everything taken out while you wait. All items inspected. Not by lowly security guards, but highly trained professionals.
People usually wait 3-5 hours to board. Physical searches are common. All checked bags go through some sort of fancy scanner. Questionable items are immediately searched.
The security guards are trained to spot irregularities, and question EACH traveler. "Where you going? Why? How long are you staying? Where are you from?"
Peopel that buy one-way tickets and are young trigger an immediate alarm, and are "harrassed" (not the word used on the newscast) to verify that they are legit passengers.
EL-AL will NOT hesitate to CANCEL a flight for ANY Suspicion they cannot find an answer to. Most flights are delayed.
Cockpit is impenentrable on the plane. Once the pilots are in there, the compartment is sealed by a vault like door. The cockpit is guarded on the plane by armed guards. In addition, there are two In-Cognito ARMED, and HIGHLY trained guards posing as passengers on every flight.
This costs El-AL with a fleet of 30+ planes several millions of dollars a year. To do this in the US was estimated to run in the billions. But everybody acknowledges that they are by far the most secure airline/airport on the planet.
Now, this was from memory on a late night newscast, and if anyone sees any errors, please correct. I tried hard to be exact!
