Noi Bai International Airport (HAN), the biggest airport in the Northern of Vietnam. It is located 28 miles (45 km) from the central city (Hanoi- The capital of Vietnam). When exiting Noi Bai International Airport, you will see lines to queue for taxis, with a sign stating that it costs $15-16 USD to Hanoi Center. There are a few companies operating this route including: Vietnam Transfer service, Viet Thanh taxi, Airport taxi and Noi Bai Taxi or Hanoi airport transfer. You will pay directly to the driver when arriving at the hotel. No toll fee or any other charge. However, this is not always the case as tourists have been overcharged, even up to $300USD for a taxi. Apart from this, beware of taxi touts. It isn’t a bad idea to arrange an airport transfer with your hotel or a travel agent in Hanoi. It’s true that you have to bargain when buy anything in Hanoi. And please note: don’t pay the drivers by the "counting clock" in their cars, first you should ask them about the price. In case that you want to save your money for the taxi, then you can catch a bus instead (they have round trip tickets available: Noi Bai-206 Trang Quang Khai Str and reverse). This bus was supported by Jet Star Pacific Airlines. The one way ticket is 40,000vnd (about 2 USD).
