Noi Bai International Airport to Hanoi

Bus Express 86 (Noi Bai – Hanoi Railway Station via Old Quarter)

Limited-stop orange express bus linking Noi Bai Airport (T1/T2) with Hanoi Railway Station via Long Bien, Hanoi Opera House and Hoan Kiem/Old Quarter area; journey is about 50–60 minutes and operates roughly 05:05–22:30 from city and 06:18–23:30 from airport depending on stop. Highly used by travelers for direct access to the Old Quarter and central hotels, with flat fare around 30,000–35,000 VND and no reservation required.

City Bus 17 (Noi Bai – Long Bien)

Local public bus from Noi Bai Airport T1 to Long Bien bus station at the edge of the Old Quarter, taking about 60–65 minutes; from Long Bien it is a short walk or taxi to Hoan Kiem Lake. Cheaper but slower and more crowded than Bus 86, with frequent daytime departures and basic onboard comfort.

City Bus 07 (Noi Bai – Cau Giay)

Local bus linking Noi Bai Airport T1 with Cau Giay in western Hanoi, where passengers can transfer to other city buses or taxis to reach the Old Quarter. Useful for budget travelers familiar with Hanoi’s bus network; runs about hourly end‑to‑end with frequent daytime departures but does not directly serve Hoan Kiem Lake.

Airline Shuttle Buses (Vietnam Airlines / Vietjet Air / others)

Shared minibuses operated by major airlines between Noi Bai Airport and central Hanoi drop-off points near the Old Quarter and major hotels, typically departing when sufficiently full. They run throughout the flight operating day, are slightly faster than city buses in light traffic, and are paid onboard in cash with fixed per-person fares.

Metered Airport Taxis (Noi Bai to Hanoi Center)

Licensed taxis queue outside both terminals and provide door-to-door service to Old Quarter and central Hanoi in about 40–60 minutes depending on traffic. Fares are usually around 350,000 VND including tolls; ensure the meter is used or agree a fixed price at the official taxi desk inside the terminal.
