KUALA LUMPUR -- Three times Tony Fernandes has tried to take AirAsia Group into Vietnam, one of Southeast Asia's fastest growing aviation markets. Three times he has failed. Now, the unstoppable head of the region's first and largest low-cost carrier is going for a fourth attempt.
But he may have met his match in Vietnam's Vietjet Aviation, which in just seven years has snapped up 45% of the local market, largely by imitating -- and sometimes topping -- AirAsia's brash, confident business model.
