The U.S. Department of Transportation said Pakistan International Airlines (PIA) had withdrawn permission to operate charter flights to the U.S., citing concerns from the Federal Aviation Administration (FAA) regarding certification of Pakistani pilots.
The information is contained in a revocation of the July 1 special permit issued by Reuters on Friday.
Pakistan grounded nearly a third of its pilots last month after finding that they may have falsified their qualifications.
The European Union's Aviation Safety Agency has suspended PIA's permit to fly into the block for six months to affect the operator's operations.
PIA was not immediately available for comments outside of normal business hours.
Pakistan's Geo News reported that PIA had confirmed the US ban and said it would address concerns through ongoing corrective action within the airline.
Pakistan's landing of pilots with dubious qualifications followed the crash of a PIA jet in May, killing 97 people.
