The signing ceremony between the sides took place in Hanoi on November 12, witnessed by President Tran Dai Quang and US President Donald Trump, during the latter’s official trip to Vietnam.
The deal also includes a 12-year EngineWise™ Fleet Management Program.
Dinh Viet Phuong, vice president of VietJet Air, said the airline is delighted to add the GTF-powered aircraft to its fleet with high hope on the engine’s efficient performance and environmental benefits.
Rick Deurloo, senior vice president of sales, marketing and customer support at Pratt & Whitney, said: “We were honored to celebrate a new relationship with VietJet last year, and we are thrilled to extend this relationship now and into the future."
Since its debut in early 2016, the GTF engine has proven its capacity to reduce fuel burn by 16 percent, emissions by 50 percent and noise footprint by 75 percent.
