Airbus is close to finalizing a major agreement with VietJet, Vietnam's largest private airline, for the purchase of 100 A321neo aircraft, with options that could increase the total to 150 planes. This deal was announced around the time of the Paris Air Show at Le Bourget and is seen as a significant boost to VietJet's growth ambitions. Separately, Airbus secured an order for 90 aircraft from the leasing company Avolon, continuing its strong momentum in aircraft sales following the airshow. Additionally, AirAsia has signed a $12.25 billion deal for 50 A321XLR aircraft, further underscoring Airbus's robust order book in the single-aisle segment.
