Any passenger who owns or legally possesses a firearm being transported aboard any common or contract carrier in interstate or foreign commerce must deliver the unloaded firearm into the custody of the pilot, captain, conductor, or operator of such common or contract carrier for the duration of the trip. Check with each carrier before your trip to avoid problems.

Bus companies usually refuse to transport firearms. Trains usually allow the transportation of encased long guns if they are disassembled or the bolts removed.
