Louisiana Revised Statutes Tit. 2, § 131. Definition; political subdivisions may acquire airports

A. “Political subdivision” as used in this Part means any parish of this state as well as any city or county of another adjoining or adjacent state which is authorized by the law of that state to engage in a joint endeavor for the creation and operation of an airport district with a political subdivision of this state. In any such joint endeavor, except to the extent manifestly inconsistent with this Part, the law of that state will govern the acquisition of lands in such other state and the appointment, term of service, and compensation for commissioners appointed by or for such city or county.

B. Cities, towns and other political subdivisions may separately or jointly, acquire, establish, construct, expand, own, lease, control, equip, improve, maintain, operate, regulate, and police, airports and landing fields for the use of aircraft, either within or without the geographical limits of such municipalities, and other political subdivisions, and may use for such purposes any available property that is owned or controlled by such political subdivisions; but no political subdivision shall exercise the authority hereby conferred outside of its geographical limits except in an adjoining political subdivision or in any adjoining political subdivision adjacent to said adjoining political subdivision and this only jointly with those political subdivisions.
