Vietnam Airlines has voiced its concerns over a plan by low-cost carrier VietJet Air to register its name as VietAir.
VietJet, which signed an agreement with Malaysia's AirAsia in April, plans to launch a low-cost airline. AirAsia has acquired a 30% stake in VietJet.
VietJet has applied to Vietnam's intellectual property office to register its name as VietAir, says the director of air transport at the Civil Aviation Administration of Vietnam, Vo Huy Cuong.
However, Vietnam Airlines also plans to use the name "VietAir" for a new joint-stock airline it is establishing.
It plans to restructure its subsidiary Vietnam Air Service (VASCO) and merge its operations with VietAir eventually, which will then provide scheduled commercial services.
"Vietnam Airlines has gone to the intellectual property office and expressed its concerns over the name VietAir," says Vo, adding that the name has not been registered yet.
Vietnam Airlines officials were uncontactable for comment.
The national carrier had previously asked the government to stop AirAsia's acquisition of a stake in VietJet, but Vietnam's transport ministry said there was no legal provision for it to do so.
