Party to whom the rights have been granted by Article I to designate an airline or airlines for the route concerned has authorized an airline for such route, and the Contracting Party granting the right shall, subject to Article VI hereof, be bound to give the appropriate operat- ing permission to the airline or airlines concerned; provided that the airlines so designated may be required to qualify before the competent aeronautical authorities of the Contracting Party granting the rights under the laws and regulations normally applied by these authorities before being permitted to engage in the operations contemplated by this Agreement.
