BANGKOK, Thailand – Thailand’s air navigation services provider says 23 airlines are now using a newly shortened flight route between Thailand and China, helping save fuel and reduce carbon emissions, with three more direct routes planned.
Aeronautical Radio of Thailand (AEROTHAI) introduced the direct-routing project under its Direct Routing for Sustainable Aviation (DRSA) programme, working with aviation authorities in Thailand, Laos and China. The first route, L770 between NAN and SAGAG, began operating on September 3, 2026.
By October 23, a total of 530 flights operated on the shortened route, reducing combined flight distances by 18,525 nautical miles, saving 112,890 kilograms of fuel and cutting carbon dioxide emissions by 357 tonnes. Twenty-three of the 26 eligible airlines are now using the route.
AEROTHAI estimates that the route could save airlines more than 40.5 million baht in fuel costs annually and reduce carbon dioxide emissions by approximately 2,561 tonnes a year.
The company is preparing three additional direct routes linking western and eastern flight corridors. It is also developing an internal DRSA Dashboard to monitor flight distances, fuel savings and greenhouse gas reductions.
Deputy Transport Minister Phatthraphong Phatthraprasit said the initiative supports more efficient and sustainable use of Thai airspace while strengthening the country’s ambition to become a world-class aviation hub. AEROTHAI President Panya Chupanich said the project forms part of the company’s wider Green Air Traffic Management initiative, combining operational efficiency, regional cooperation and environmental responsibility.
