Local private airlines are stuck on the ground without sufficient capital and human resources, the Civil Aviation Administration of Vietnam said in a report.
According to the report, which has been submitted to the Ministry of Transport, none of the three licensed private airlines are currently operating flights.
Indochina Airlines, the first private airline to run flights in Vietnam, has suspended its services due to debt problems. The carrier will have its business licensed revoked in October if it fails to resume service by then.
Meanwhile, VietJet Air received its license in December 2007 but it has delayed its first flight several times since. The airline said it needs more time to obtain an Air Operator Certificate.
Vo Huy Cuong, head of the Civil Aviation Administration of Vietnam's Air Transport Department, said both of the airlines don't have Air Operator Certificates, which prove that a carrier has met all capital and personnel requirements.
The third private airline, Mekong Air, said it would launch its first flight in October this year. But Cuong said the carrier has not submitted any specific plans to the aviation administration.
