FlightScreening.com is a free reference for U.S. airport security screening rules. It answers a single practical question: whether a specific item can go in your carry-on bag, your checked bag, or neither.
You can search for an item, browse a category, or read a guide without creating an account or providing any information.
Each page summarizes guidance published by the Transportation Security Administration and presents it in a consistent format: a short answer for carry-on bags, a short answer for checked bags, and the safety reason behind the rule where one is stated.
Where an official source exists, it is linked so you can read the original wording. The official source for these rules is TSA.gov.
The home page opens with a search box. From there you can reach an individual item page, a category of related items, or a guide covering a broader topic such as the 3-1-1 liquids rule or trusted traveler programs.
Every page is listed in the complete A-Z index, and recurring questions are collected on the FAQ page.
Pages are reviewed as published guidance changes. Screening rules can change without notice, and a summary may lag behind the current wording, so confirm anything important directly with the official source before you travel.
