United States Bans Pakistan International Airlines

Washington: The US Department of Transportation announced that they have suspended Pakistan International Airlines (PIA) at least for six months on Friday (July 10). After Europe, the United States became second to revoke the permission to conduct flights in the region due to the concern over Pakistani pilot certification. PIA spokesperson Abdullah H Khan told that "It is a major setback for us." He added to the statement that they have been planning to restart regular flights from Pakistan to the US.

PIA have been facing major issues regarding the finance for years. The US officials declared that the ban had been announced because of the recent issue of suspected pilots license in PIA. To notify, many other countries have also suspended pilots who holds Pakistani aviation license after the fake license scandal came out. Pakistan have almost grounded a third of its pilots last month after discovering the fact that they might be having falsified qualification.

On May 22, around 97 people had died in a crash in Karachi in a Pakistan International Airlines. Pakistan Aviation Minister had himself informed the authorities that a huge number of pilots are having a fake qualification in the field or have done cheating in the examination of aviation.
