The Screening Experience

Everyone who travels by air goes through airport security checkpoints.  These checkpoints are operated by Transportation Security Officers from the Transportation Security Administration.

The checkpoints are there to make sure that terrorists can’t bring anything aboard the plane that would enable them to take it over or destroy it. These are called “prohibited items” and cannot be brought to a checkpoint, into the secure area of an airport, or aboard an aircraft.

Not only do all passengers go through checkpoints, their checked baggage is also screened. This may happen out of passengers' view depending on the physical configuration at each airport.

It's a good idea to prepare before you arrive at the airport so that you move more quickly and efficiently through the security process. Here are some suggestions to help make the process as smooth as possible.

Dress the Part

There’s no particular style or type of clothing that you should wear from a security point of view. You are permitted to wear head coverings and religious garments during the screening process. You may be directed to additional screening if your clothing (religious or otherwise) is loose fitting or large enough to hide prohibited items. For more information, click here.

In addition, certain clothing and accessories can set off an alarm on the metal detector and slow you down. Avoid wearing clothing, jewelry or other accessories that contain metal when traveling through the security checkpoints:  

Disposable booties or slippers may be worn through the checkpoint to help protect your feet, but they must be disposed of prior to leaving the screening area.

Gel-filled bras are permitted through security screening and aboard aircraft.

TSA Security Officers have to identify any metal that is detected at the checkpoint.  If you set off the alarm, you will undergo additional screening.  This includes a hand-wand and pat-down inspection.

You can remove metal items at the security checkpoint and place them in the plastic bags offered at several airports or in the bins provided.  The bins will be sent through the X-ray machine.  You can save time by not wearing metal items or by placing them in your carry-on baggage before getting in line.

What you need

We encourage each adult traveler to keep his/her airline boarding pass and government-issued photo ID available until exiting the security checkpoint (children are not required to show identification). The absence of proper identification will result in additional screening.

There are four ways to obtain a boarding pass:

If you aren't traveling and need to go through the security checkpoint to accompany someone such as a child or other traveler with medical conditions who is traveling, check with the airline for required documentation.

Do I Have to Remove My Shoes?

Yes, you are required to remove your shoes before you enter the walk-through metal detector. This includes all types of footwear.

Due to the Homeland Security threat level being raised for the U.S. aviation sector worldwide this is critical to protect the world's travelers who transit by air to and from the United States.

Our Security Officers will ask that you remove your shoes before entering the metal detector based on the fact that many types of footwear can be used to carry prohibited items. When a Security Officer asks you to remove your shoes, please do. If you refuse, you will not be able to board your flight.

You are required to remove your shoes before you enter the walk-through metal detector. All types of footwear must be placed on the X-ray machine to be screened. If you do not comply with Security Officers, you will not be allowed to board your flight

Keep Your Experience Simple

Take metal items such as keys, loose change, mobile phones, pagers and personal digital assistants (PDAs) out of your pockets. Put these in your carry-on, or in a plastic bag. This keeps lines moving and your experience more pleasant. Try to avoid wearing anything with metal, clothing, jewelry or other accessories that contain metal such as, heavy jewelry, clothing with metal buttons or snaps, belt buckles or under-wire bras.

Pack your coats and jackets in your baggage when possible.  All coats and jackets that you are carrying must go through the X-ray machine for inspection.  If you choose to wear an outer coat or jacket to the checkpoint, you will need to either pack it in your carry-on baggage or put it in one of the bins we provide.

You may be additionally screened because of hidden items such as body piercings, which alarmed the metal detector.  If you are selected for additional screening, you may ask to remove your body piercing in private as an alternative to a pat-down search.

Travel Tips To Make Your Screening Experience Hassle-free

Items purchased in the secure boarding area are for use on the immediate flight. If you must leave the secure boarding area and re-enter through the screening checkpoint, items exceeding 3 ounces that are not in the zip-top bag will again be prohibited.

The ban on liquids, aerosols and gels was implemented on August 10 after a terrorist plot was foiled. Since then, experts from around the government, including the FBI and our national labs have analyzed the information we now have and have conducted extensive explosives testing to get a better understanding of this specific threat. These changes are intended to enhance security and balance human needs because we have a better understanding of the threat and security risks associated with liquids, aerosols and gels.

In addition, TSA will be enhancing security measures throughout the airport environment – more random screening of employees, additional canine patrols, stronger air cargo security measures, more rigorous identity verification, deploying more trained security officers in bomb appraisal, and screening by observation techniques.

On Tuesday, September 26 2006, we adjusted the ban on liquids, gels, and aerosols.

Air travelers may now carry liquids, gels and aerosols in their carry-on bag when going through security checkpoints.

With certain exceptions for prescription and over-the-counter medicines, baby formula and breast milk, and other essential liquids, gels, and aerosols, the following rules apply to all liquids, gels, and aerosols you want to carry through a security checkpoint.


All liquids, gels and aerosols must be in three-ounce or smaller containers. Larger containers that are half-full or toothpaste tubes rolled up are not allowed. Each container must be three ounces or smaller.


All liquids, gels and aerosols must be placed in a single, quart-size, zip-top, clear plastic bag. Gallon size bags or bags that are not zip-top such as fold-over sandwich bags are not allowed. Each traveler can use only one, quart-size, zip-top, clear plastic bag.


Each traveler must remove their quart-sized plastic, zip-top bag from their carry-on and place it in a bin or on the conveyor belt for X-ray screening. X-raying separately will allow TSA security officers to more easily examine the declared items.

Please keep in mind that these rules were developed after extensive research and understanding of current threats. They are intended to help air travelers bring essential toiletries and other liquids, gels and aerosols for short trips. If you need larger amounts of liquids, gels and aerosols such as toothpaste or shampoo, please place them in your luggage and check them with your airline.

Please note that some liquids and gels are currently prohibited. The list of prohibited items can be seen by clicking here.
