Vietnam has three major international airports, all with direct flights from Taiwan. If you wish to travel to Hanoi, the northern capital, you can do so by flying to Noi Bai International Airport (HAN), the airport about 45 kilometers worth making it since the person is targeting Hanoi City. Currently, there are several airlines running direct flights from Taipei to Hanoi. For instance, China Airlines, EVA Air, Vietnam Airlines, and a budget airline, namely VietJet Air, are all running flights onto Hanoi from Taipei. The entire trip takes roughly 2 hours and 55 minutes.
