Vietnam Airlines, Vietjet Air, and Vietravel Airlines have submitted operating plans for Long Thanh International Airport ahead of its commercial launch in December 2026. Vietnam Airlines will transfer approximately 12% of its international flights from Tan Son Nhat to Long Thanh, while Vietjet commits to maintaining at least two international routes in Phase 1. Vietravel plans to commence operations by end of 2026, increasing frequencies from summer 2027. The Airports Corporation of Vietnam (ACV) promotes 21 new routes to enhance the airport’s attractiveness. Operational trials are scheduled between September and November 2026, with full commercial operations expected in the fourth quarter. Long Thanh will serve as a new international gateway, reducing pressure on Tan Son Nhat and expanding Vietnam’s aviation capacity.
