Environment Vietnam Airlines participates in "The Sustainable Flight Challenge" 06/09/2022 Vietnam Airlines and 15 international airlines participated in Skyteam's “The Sustainable Flight Challenge", with the first flight numbered VN416 from Hanoi to Seoul on May 14. Airlines will compete in this program to demonstrate their ability to operate the most environmentally sustainable flight. Passengers on the flight were given a cloth bag and a message card made from environmentally friendly materials. Vietnam Airlines' fleet is constantly being upgraded, including Airbus A350, Boeing 787 and A321neo with new generation engines, helping to reduce 50% of emissions, 16% of fuel usage and 75% of noise compared to the old generation. Since 2019, Vietnam Airlines has stopped using plastic bags to wrap supplies and commodities on board, resulting in a reduction in the use of more than 60 million plastic bags per year.
