karachi - Pakistan International Airlines first direct flight from Sialkot to Dubai that was to leave on November 30 will not operate as scheduled because Dubai Civil Aviation Authorities have so far not given the required permission, Airline spokesperson said. PIA had planned direct flights between Sialkot and Dubai from November 30, and had applied in October for Civil Aviation Department (CAD) permission from Dubai Civil Aviation as per agreement between Govt of Pakistan and United Arab Emirates. He said that bilateral air services agreement between Pakistan and UAE allows the designated airlines of Pakistan to operate unlimited frequencies from any point in Pakistan to Dubai. Similarly, he added, the designated airlines of UAE are entitled to operate unlimited frequencies between Dubai and Karachi. Moreover, the UAE airlines are allowed operation of eleven more frequencies per week to three conditional gateways Karachi, Lahore and Islamabad, he said. Until Thursday, November 26, permission was not received by PIA to operate this sector, he added. Due to Eid holidays it way not be possible for CAD permission to arrive by Nov 30, so it may not be possible for PIA to operate the direct flight from Sialkot to Dubai as planned. PIA is making alternate arrangements to carry 40 passengers already booked from Sialkot to Dubai and 70 passengers booked on the return sector from Dubai to Sialkot. The delay in grant of approval by the department of civil aviation Dubai has resulted in disturbing PIAs inaugural flight and launching of Sialkot-Dubai sector, he added. Other six Emirates of UAE have never violated the bilateral air services agreement and have always granted permission for flights to all airlines of Pakistan, though, this is the first incident of delaying permission to PIA, the civil aviation authorities of Dubai have in the past denied Shaheen Air the permission to operate to Dubai. Emirates Airline is presently operating 28 weekly flights to Karachi and eleven flights to other gateways. It has never been refused permission to increase its flights to Karachi as allowed in the bilateral air services agreement. While, the Emirates Airline has been making efforts for gaining more traffic rights from Pakistan.
