In advance of the upcoming changes to TSA’s Prohibited Items List, effective April 25, 2013, the guidelines below on small knives permitted in carry-on luggage are provided to help passengers prepare for airport security procedures prior to checkpoint arrival.

TSA continues to evolve and strengthen its multi-layered approach to aviation security – through better technology, expanded data analysis capabilities and an enhanced understanding of current intelligence. The decision to permit certain items in carry-on luggage was made as part of TSA’s overall risk-based security approach and aligns TSA with International Civil Aviation Organization Standards and our European counterparts.

Small knives permitted in carry-on luggage must meet all of the following requirements:

Permitted:
