Can a Cop Carry a Gun on a Plane???

Just wondering if cops can carry guns on planes. I know federal agents can but I was curious about local law enforcment.

Thanks

If a law enforcement officer wants to carry he must get a letter from his chief saying he is allowed to carry. Then he must get approval from the airlines. Its a big hassel. I would just rather drive my car and carry instead of getting all the crap to carry on a plane.
