Noi Bai International Airport (HAN) is Hanoi’s main international gateway and typically serves full-service carriers and many regional airlines, making it the city’s principal hub for long-haul and international connections. Located about 45–50 km (roughly 40–60 minutes without heavy traffic) north of downtown, it’s usually reached by shuttle coach, taxi or ride-hail; public buses and airport express services can take around 60–90 minutes with fares varying modestly. The airport tends to be more comfortable with a wider range of lounges, shops and transport options, but can feel busy in peak periods and ground transfers may be slower and costlier than smaller airports.
Noi Bai also handles many low-cost and domestic flights, so travelers often find a mix of price points and carrier types. Ground transport choices include airport buses (economical), metered taxis (convenient) and app-based cars (flexible); fares and journey times can fluctuate with traffic and time of day. For those prioritizing international connections and amenities, Noi Bai is usually the most practical choice, while budget-minded passengers can often find cheaper fares on domestic routes that use the same airport but sometimes board from different terminals.

Phnom Penh International Airport (PNH) serves as Cambodia’s main international gateway and usually handles the bulk of scheduled long‑haul and regional services, alongside a growing number of low‑cost carriers. The airport sits about 10–12 km east of the city centre, with taxis and ride‑hailing apps typically taking 20–35 minutes depending on traffic; fares can often range from modest flat rates to slightly higher metered amounts. Public buses and hotel shuttles provide cheaper if slower options. As a mid‑sized hub it can be more straightforward than larger Asian airports, but peak‑hour congestion and occasional delays are possible; travelers often find a reasonable balance of basic amenities and quick access to central Phnom Penh.
