1. Taxi: The most convenient way from the city center to Hanoi International Airport is by taxi. You can find taxis lined up at various spots across the city, such as at the main bus terminal or on the street level outside the major hotels and shopping areas.
2. Private car rental: If you want your own car, you can rent out a car from the local rental agency in Hanoi. This also gives you flexibility and control over your journey, whereby you choose the route and time you want it to take. However, rent a car may be expensive and even more so for longer distances than public transport.
3. Taxi express: If you have lots of luggage and are short of time, you may consider taking an express airport taxi. These vehicles are specially meant for this airport transfer situation and bring you from your door to the airport entrance with a driver who will pick you up and drop you off. The regular scheduled airport express taxi requires excess charge for the convenience service.
4. Airport train: Another option is to take the train from the central station in Hanoi to the airport. This daily service via the Hanoi-Hai Commuter Rail Line makes travel to the airport comfortable and efficient with an average ride of 20-30 minutes and charges an estimated 90,000 VND (approximately USD $3.60). This mode may not be adequate for long-distance travel, but the train is a convenient form of transport for close-haul flights and budget-travelers.
