49 U.S.C. § 41713 — Preemption of authority over prices, routes, and service

(a) “State” means a State, the District of Columbia, or a United States territory or possession.

(b)(1) Except as this subsection provides, a State, its political subdivision, or a political authority of at least two States may not enact or enforce a law or other rule having the force of law that relates to an air carrier’s price, route, or service when the carrier may provide air transportation under this subpart. (2) Paragraphs (1) and (4) do not apply to air transportation entirely within Alaska unless it is noncharter transportation under a section 41102 certificate. (3) This subsection does not limit an airport-owning or airport-operating State authority from exercising its proprietary powers and rights when the airport is served by a carrier with a Secretary-issued certificate. (4)(A) Except under (B), the same State authorities may not enact or enforce such a rule relating to the price, route, or service of an air carrier or a commonly controlled affiliate of a direct air carrier when transporting property by aircraft or motor vehicle, whether or not the property has had or will have air movement. (B)(i) This does not restrict State motor-vehicle safety regulation, highway route controls or limits based on vehicle size, weight, or hazardous cargo, or State regulation of motor carriers concerning minimum financial responsibility for insurance and self-insurance. (ii) It does not apply to household-goods transportation as defined in section 13102. (C) Paragraph (4) does not limit paragraph (1).
