TSA won't care it's Halloween. You can't travel with these things

TSA warns travelers that Halloween celebrations do not exempt them from security protocols. While dressing up for the holiday is encouraged for people of all ages, the agency advises passengers to wait until they have passed through airport security before putting on their costumes. Certain items associated with Halloween attire may be prohibited during travel, and security personnel will strictly enforce these rules regardless of the holiday to ensure safety and efficiency within the airport environment.
