Artikel 9

1). The tariffs to be charged by the airline of one Contracting Party for carriage to or from the territory of the other Contracting Party shall be established at reasonable levels, due regard being paid to all relevant factors, including cost of operation, reasonable profit, and the tariffs of other airlines.
2). The tariffs referred to in paragraph (1) of this Article shall, if possible, be agreed by the designated airlines of both Contracting Parties after consultation with the other airlines operating over the whole or part of the route and such agreement shall, wherever possible, be reached by the use of the procedures of the International Air Transport Association for the working out of tariffs.
3). The tariffs so agreed shall be submitted for approval to the aeronautical authorities of both Contracting Parties at least ninety (90) days before the proposed date of their introduction. In special cases, this period may be reduced subject to the agreement of the said authorities.
4). The approval referred to in paragraph (3) of this Article may be given expressly. If neither of the aeronautical authorities has expressed disapproval within thirty (30) days from the date of submission in accordance with paragraph (3) of this Article, these tariffs shall be regarded as approved. In the event of the period for submission being reduced as provided for in paragraph (3) the aeronautical authorities may agree that the period within which any disapproval must be notified shall be less than thirty (30) days.
5). If a tariff cannot be agreed in accordance with paragraph (2) of this Article, or if, during the period applicable in accordance with paragraph (4) of this Article, one aeronautical authority gives the other aeronautical authority notice of its disapproval of a tariff agreed in accordance with the provisions of paragraph (2) of this Article, the aeronautical authorities of the two Contracting Parties shall endeavour to determine the tariff by mutual agreement.
6). A tariff established in accordance with the provisions of this Article shall remain in force until a new tariff has been established. Nevertheless, a tariff shall not be prolonged by virtue of this paragraph for more than twelve (12) months after the date on which it would otherwise have expired or the date of the giving of a notice of disapproval of that tariff under paragraph (5) of this Article, whichever shall be the earlier.
