What are the laws on police officers carrying their weapons on public planes?

Hank: What are the laws on police officers carrying their weapons on public planes?
What are the laws/revised codes for police officers carrying their duty weapons on board a public airline?

If all you’re going to say is “They can’t” or “They can”, then please cite a source. Just doing a bit of research on the topic, but I can’t seem to find too much info from any legit source, such as code of federal regulations, or FAA guidelines, etc.

Thanks!

Generally a police officer can not carry a weapon in a loaded state on their person in a commercial plane. They can however carry it according to federal law which entails certain forms to be filed and notification made to the pilot. FAA requires that weapons be unloaded, stowed in hard-sided, locking luggage, and declared at the main ticket counter at the time of check-in. At check-in, you will receive proper documentation to place inside the gun case indicating that the weapon had been declared. In certain cases you may be allowed to leave it in the cockpit. Certain federal law enforcement officers may carry a concealed weapon on a plane. Although they still need to file paperwork and notify the pilot.

A police officer may be granted special permission to carry a concealed weapon if they are in the performance of their official duty and transporting a prisoner. This is usually a U.S. Marshal’s job but exceptions can be made under certain circumstances.
