The international airport that serves Hanoi is Noi Bai International Airport (HAN): situated about 29 kilometers north-east of downtown Hanoi. The distance apart requires some consideration of traffic and exact locations within Hanoi; nonetheless, a vehicle or taxi drive usually takes 45 minutes to an hour.
The distance from Hanoi to Noi Bai International Airport, which is the main airport serving Hanoi, Vietnam, is approximately 45 kilometers (about 28 miles). The travel time by car or taxi usually takes around 30 to 45 minutes, depending on traffic conditions.
There is an approximate distance which depends on the airport you would be typing about. Here are some generalized approximations:
It costs about VND1,250 (approximately USD34), and the trip from Hanoi's main international airport, Noi Bai International Airport, takes about an hour, covering a distance of about 1,600 meters (6,900 feet) to downtown.
It costs about VND7,500 (around USD23), and takes 30-45 minutes to ride the public bus (in some scenarios), which would probably cover a distance of about 8 km (5 miles) to downtown Hanoi, including Hoan Kiem Lake area, where most of the neighboring attractions are.
It costs about VND10,000 (approximately USD32). If you prefer to take a much more direct trip to downtown Hanoi in about 40 minutes with a number of stops along the way, you could take a train. The Vietnam Railway System provides express connections between those two cities, and the options include an overnight train to regular scheduled services.
It costs about VND30,000 (about USD96). There is a new level of competition between local service providers deploying great shuttle services between Hanoi's airport and various spots within the city-such as the Hanoi Old Quarter, Hoan Dinh Lake, or the historic city walls, offered at standard rates or luxury standards in case you're seeking more comfort or luxury features.
