Artikel 11

1. Each Contracting Party shall use its best efforts to ensure that the User Charges imposed or permitted to be imposed by its competent charging bodies on the Designated Airlines of the other Contracting Party for the use of airports and other aviation facilities are just and reasonable. These charges shall be based on sound economic principles and shall not be higher than those paid by other Airlines for such services.
2. Neither Contracting Party shall give preference, with respect to User Charges, to its own or to any other Airline(s) engaged in similar International Air Services and shall not impose or permit to be imposed, on the Designated Airline(s) of the other Contracting Party User Charges higher than those imposed on its own Designated Airline(s) operating similar International Air Services using similar aircraft and associated facilities and services.
3. Each Contracting Party shall encourage consultations between its competent charging bodies and the Designated Airlines using the services and facilities. Reasonable notice shall be given whenever possible to such users of any proposal for changes in User Charges together with relevant supporting information and data, to enable them to express their views before the charges are revised.
