The Vietnamese low-cost airline, which started to fly in late 2011 , recently has finalised an order with Airbus Group to purchase and lease 100 aircraft with a total contract value of US$9.1 billion.
According to Nguyen Thanh Hung, Vice Chairman of VietJetAir, the airline transported more than 4.3 million passengers last year, accounting for about 26 percent of domestic market share.
After more than two years of operation, the airline now has a fleet of 11 leased A320s. Besides domestic destinations, the carrier also flies to Bangkok, Seoul and China’s Kunming.
The carrier plans to open a direct route from Vietnam to Singapore this year and other routes to North East Asia in the time to come.
