I'll be flying cross country this summer with my pistol, so I conducted some research regarding flying with a firearm. Hope this is useful to others: Here is a link to a reciprocity map for concealed handgun licenses across the U.S. Click on the state in which you hold a CHL and it will show which other states honor that license. Other useful links: TSA policy Southwest Airlines policy Delta Airlines policy United Airlines policy American Airlines policy Most airlines appear to have the same policy regarding procedure: 1. Firearm must be declared when checking in 2. Firearm must be unloaded and secured in a locked, hardshell container 3. The key must remain in your possession at all times except during inspection of the firearm by a TSA official when you first check your luggage (this will happen in your presence and the key will be returned to you immediately after the visual inspection) 4. Maximum 11 lbs. of ammunition, must be secured in its box or a container designed for carrying ammunition; if ammunition is being transported in a magazine then the magazine must be secured in a proper pouch/holder such that the ammunition is not visible when the pouch/holder is closed. You will also want to verify the carry restrictions in the state to which you are traveling, or ANY state in which you will be retaking possession of your firearm from the airlines and whether or not you can carry, transport, or possess in that state. This info is based on one passenger traveling with a single, personally owned firearm. Other laws may restrict travel with multiple firearms. If anyone else has useful info, please add links in here.
