Section 37-9-27 - Air carriers to file tariff of rates, fares and charges; rejection of tariff and consequences thereof; refunds or remittances of rates, fares and charges; changes in rates, fares and charges; filing of divisions of joint rates, fares and charges(a) Every common carrier by aircraft shall file with the commission, print and make available to the public, tariffs showing all the rates, fares and charges for the intrastate transportation of persons or property within the state between points served by it, and between points served by it and points served by any other common carriers when through intrastate service and rates have been established, and all classifications, rules, regulations, practices and services in connection with such transportation.(b) Every contract carrier by aircraft shall file with the commission, print and make available to the public, tariffs showing all minimum rates, fares and charges for the intrastate transportation of persons or property within the state, and all classifications, rules, regulations, practices and services in connection with such transportation.(c) Air carrier tariffs shall be filed, printed and made available to the public to the extent and in the manner required by reasonable regulations of the commission. The form of such tariff shall be prescribed by the commission and shall conform as nearly as may be to the form of tariffs required of air carrier and air contractors by the Civil Aeronautics Board or other administrative agency of the federal government under the Act of Congress entitled, "The Civil Aeronautics Act of 1938," approved June 23, 1938, and the acts amendatory thereof and supplementary thereto. The rates, fares and charges shown in any tariff shall be stated in terms of lawful money of the United States.(d) The commission is empowered to reject any tariff which is not consistent with this section and the reasonable regulations of the commission thereunder. Any tariff so rejected shall be void.(e) No common carrier by aircraft shall charge or demand or collect or receive a greater or less or a different compensation for the intrastate transportation of persons or property, or for any service in connection therewith, than the rates, fares and charges specified in its currently effective tariff; and no common carrier by aircraft shall in any manner or by any device, directly or indirectly, or through any agent or broker, or otherwise, refund or remit any portion of the rates, fares or charges so specified or extend to any person any privileges or facilities, with respect to matters required by the commission to be specified in such tariffs, except those specified therein. In the event that an excessive rate, fare or charge is stated in a currently effective tariff through error, the common carrier by aircraft may, in accordance with the regulations prescribed by the commission, make appropriate refunds to any persons paying such charge.(f) No contract carrier by aircraft shall charge, demand, collect or receive a less compensation for the transportation of persons or property, or for any service in connection therewith, than the rates or charges specified in its currently effective tariffs; and no contract carrier shall in any manner or by any device, directly or indirectly, or through any agent or broker, or otherwise, refund or remit any portion of the compensation for such transportation so as to reduce such compensation below the rate, fare or charge so specified or extend to any person any privileges or facilities, with respect to matters required by the commission to be specified in such tariffs, except those specified therein. In the event that an excessive minimum rate, fare or charge is stated in a currently effective tariff through error, the contract carrier may, in accordance with regulations issued by the commission, make appropriate refunds to any persons paying such charge.(g) Nothing in this chapter shall prohibit air carriers, under such reasonable terms and conditions as the commission may prescribe, from issuing or interchanging tickets or passes for free or reduced-rate transportation to their directors, officers and employees and their immediate families, witnesses summoned by them and attorneys duly employed by them and actually attending any legal investigation in which such air carrier is interested, persons injured in aircraft accidents and physicians and nurses attending such person or any person or property with the object of providing relief in cases of general epidemic or of calamity. No air carrier shall provide free or reduced-rate transportation to any other persons or under any other circumstances.(h) No change shall be made in any rate, fare or charge in or any classification, rule, regulation or practice affecting any such rate, fare, charge or the value of the service thereunder, specified in any effective tariff or any common carrier by aircraft, except after 30 days notice of the proposed change filed, printed and made available to the public in accordance with subsections (a) and (c) of this section. Such notice shall plainly state the change proposed to be made and the time such change will take effect. The commission may, in the public interest, by regulation or otherwise, allow such change upon notice less than that herein specified or required in this section with respect to filing and posting of tariffs, either in the particular instance or by general order applicable to specific or peculiar instances or conditions; provided, that such action on the part of the commission shall in no way work a discrimination against any person.(i) No reduction shall be made in any rate, fare or charge, specified in any effective tariff of any contract carrier by aircraft, and no change shall be made in any classification, rule, regulation or practice affecting any such rate, fare or charge, or the value of the service thereunder, except after 30 days notice of the proposed reduction or change filed, printed, and made available to the public in accordance with subsections (b) and (c) of this section. Such notice shall plainly state the reduction or change proposed to be made and the time such reduction or change will take effect. The commission may, in the public interest, by regulation or otherwise, allow such reduction or change by notice less than that specified herein; provided, that such action on the part of the commission shall in no way work a discrimination against any person.(j) Every common carrier by aircraft shall keep currently on file with the commission, if the commission so requires, the established divisions of all joint rates, fares and charges for air transportation in which such common carrier participates.
