The following information was provided by the Transportation Security Administration.

Prohibited items are weapons, explosives, incendiaries, and include items that are seemingly harmless but may be used as weapons - the so-called "dual use" items. You may not bring these items to security checkpoints without authorization.

If you bring a prohibited item to the checkpoint you may be criminally and/or civilly prosecuted or at the least asked to rid yourself of the item. A screener and/or Law Enforcement Officer will make this determination depending on what the item is and the circumstances. This is because bringing a prohibited item to a security checkpoint - even accidentally - is illegal.

• Your prohibited item may be detained for use in an investigation and if necessary as evidence in your criminal and/or civil prosecution. If permitted by the screener or Law Enforcement Officer, you may be allowed to:
   
• Consult with the airlines for possible assistance in placing the prohibited item in checked baggage
   
• Withdraw with the item from the screening checkpoint at that time
   
• Make other arrangements for the item such as taking it to your car
   
• Voluntarily abandon the item. Items that are voluntarily abandoned cannot be recovered and will not be returned to you.

Please refer to the printable versions of the prohibited and permitted items list above where you will find a list of items that are permitted or prohibited in your carry-on or checked baggage. You should note that some items are allowed in your checked baggage but not your carry-on. Also pay careful attention to the 'Notes' included at the bottom of each section - they contain important information about restrictions.

The prohibited and permitted items list is not intended to be all-inclusive and is updated as necessary. To ensure everyone's security the screener may determine that an item not on this chart is prohibited.

The list of items applies to flights originating within the United States. Please check with your airline or travel agent for restrictions at destinations outside of the United States.
