Dong Hoi Airport is the principal operating aviation gateway for Đồng Hới, Phong Nha–Kẻ Bàng and northern post-2025 Quảng Trị. The airport operates with a 2,400 m × 45 m runway and T1, whose design capacity is 500,000 passengers per year. Its defining 2026 development is Passenger Terminal T2, under construction with design capacity of 3 million passengers per year and provision for expansion to 5 million after 2030.

Overview
Understand the airport as a journey, a gateway and a regional transport system.
Đồng Hới Airport combines a relatively compact operating footprint with an outsized tourism role because it is the air gateway to the Phong Nha–Kẻ Bàng cave-and-karst region. The current passenger terminal T1 is approximately 4,282 m² and designed for 500,000 passengers annually, while the single runway measures 2,400 m × 45 m. ACV began construction of T2 in April 2025. Provincial reporting in 2026 shows the terminal progressing toward a targeted late-2026 opening, but VietnamWaving keeps T2 firmly in the under-construction category until official commissioning is confirmed. The July 2026 national airport-system plan continues to classify Đồng Hới as a domestic airport.

Know before you assume
Common airport misconceptions
Đồng Hới Airport is now in post-merger Quảng Trị Province; older sources correctly place it in former Quảng Bình.
T2's 3-million-passenger design capacity is not current operating capacity while the terminal remains under construction.

The airport has one 2,400 m × 45 m runway.
Đồng Hới remains classified as a domestic airport in the July 2026 national airport-system plan.
The developing Quảng Trị Airport is a separate airport and should not be confused with Đồng Hới Airport.
