VietJetAir has placed an order for 63 Airbus A320 jets with a list price of $US6.4 billion ($A7.17 billion) in a massive expansion drive by the privately owned budget carrier founded only in 2011.
The deal, signed on the opening day of the Singapore Airshow on Tuesday, also covers rights to acquire or lease additional A320s potentially boosting VietJetAir's current fleet of 11 A320s tenfold.
"The A320 has proven to be extremely efficient in service with VietJetAir and is a favourite with our passengers," the firm's managing director Luu Duc Khanh said in a press statement issued by Airbus.
The low-cost carrier currently has a fleet of 11 leased A320s plying domestic routes as well as services to Bangkok, Seoul and Kunming in China.
"We look forward to developing our business across the Asia Pacific region," Luu said, adding that Airbus would be a "strategic partner" in its regional expansion.
