Noi Bai International Airport (HAN) is Hanoi’s primary international gateway and the city’s main full-service hub, handling the majority of long-haul and regional flights alongside major carriers and Vietnamese full-service and low-cost airlines. Located about 45–50 km (roughly 45–60 minutes without heavy traffic) north of the city centre, it can be reached by airport shuttle bus, hotel transfer, taxi or ride-hailing services; expect shuttle fares and public-bus fares to be modest while taxis/ride-hails vary by distance and time of day. Pros: a wide range of airline choices, modern terminals and duty-free shopping; cons: the trip to downtown can be time-consuming in peak traffic and some services may be crowded during holiday periods.

Wattay International Airport (VTE) serves as Vientiane’s main international gateway and typically functions as Laos’s primary hub for both regional and some long-haul services. You’ll usually find national carrier Lao Airlines alongside several Southeast Asian full-service and low-cost operators; fares can be competitive for nearby destinations but may run higher than larger regional hubs. The airport sits roughly 3–5 km north of the city center — a taxi or tuk‑tuk commonly takes about 10–20 minutes depending on traffic, often costing a few dollars; some hotels offer shuttles. Pros: compact layout, short transfer times and straightforward immigration; cons: limited shopping and lounge options, and fewer flight frequencies compared with major Asian hubs.

The cost of a one-way flight from Hanoi to Vientiane ranges from $109 (September 2026) to $184 (February 2027). On average, the ticket price is about $139–$142.
