A bomb threat delayed a Pakistani passenger flight bound for Dubai by four hours on Thursday, with officials clearing it to take off after searches found no explosive device on board.
"The plane has been thoroughly searched and no bomb was found, it has taken off at 3:00 pm," Hasan told AFP.
Last month, a PIA jet was forced to land shortly after takeoff from Karachi after a passenger made a hijack threat.
The state carrier is on the verge of going bust, but provides the only direct services from Pakistan to Britain, Europe and North America.
