Noi Bai Airport is a small airport compared to Tan Son Nhat airport in Ho Chi  Minh City, but it has newer and more modern Terminal 1 until August 2007 when International Terminal 2 of Tan Son Nhat Airport opened. A larger  international airport is  also planned  for Hanoi, for which  loans have already been secured. It has a new 3,800 m paved runway and an old 3,200 m paved runway . The distance between the two runways at Noi Bai Airport  is just 250m, therefore Noi Bai International Airport has a maximum capacity of 10 million passengers per year in accordance with ICAO safety regulations. Arrival and Departure flights are currently operated in the same airport location ( UP FLOOR for departure and DOWN FLOOR for arrival).

Tan Son Nhat Airport is currently Vietnam's largest international airport in terms of area and capacity( with maximum 15-17 million passengers per year) and also the country's largest airport in terms of passengers serves Ho Chi Minh City in particular and  Dong Nam Bo in general in Southern Vietnam.  A new International Terminal 2 funded by Japanese ODA and constructed by a consortium of four Japanese contractors openned in September 2007 with the capacity up to 8-10 million passengers per year, giving this airport a really commercial hub status in the entire Vietnam. The old terminal is now to be used for domestic flights only( arrival/departure) and is just 10 miinutes walking to the Terminal 2.
