All baggage must be scanned before being put on the airplane. Baggage that is checked in for loading is scanned as it goes through the conveyor system to the trucks that take it to the planes. Carry on baggage is set on a conveyor at a security check point and scanned. A security officer watches the screen and evaluates whether it needs further study. If the bag is deemed suspicious, the officer will notify another security officer to pull you out of line so that you can witness the search.
Individuals are scanned by walking through a metal detector. Anything that could or does set the detector off, must be placed in a dish for examination. Shoes must be taken off and sent through the scanner as well. Some items that are not allowed on an airplane include knives, box cutters, scissors, other sharp objects, large sports equipment such as baseball bats, guns, aerosol and tools. Some of these items are allowed to be checked in with stored baggage, but none are allowed on the plane where the passengers are located.
Have your driver's license or passport and boarding pass ready at the scanning check point. Individuals without a boarding pass are not allowed to go past this check point and ID is required to prove that you are the individual on the pass.
