The airline has provided them with food, but not arranged hotel rooms
Vietnam last month grounded all Pakistani pilots working for local airline amid concern from global regulators that some pilots may have been using dubious licences.
"All licenses administered by the Pakistani aviation regulator are legitimate and valid. There are no fake licenses, as mentioned by the media," a government statement said, citing a note from the Pakistani Embassy to the Vietnamese government.
Vietnam had licensed 27 Pakistani pilots and 12 of them were still active. The other 15 pilots' contracts had expired or were inactive due to the coronavirus pandemic, according to Vietnam's Civil Aviation Authority.
