Flights Bangkok → Hanoi (BKK-HAN) — THB Fares, Airlines, Frequency

Bangkok to Hanoi links Thailand with Vietnam’s capital, a route running on business travel, tourism and regional family ties. At around 35 flights a week it is frequent and dependable, carrying visitors to Hanoi’s old quarter and the landscapes of northern Vietnam alongside a steady stream of business passengers.

Block time is about 1.8 hours — a short hop. The mix of full-service and low-cost carriers keeps the route competitive, and Hanoi also serves as the gateway to northern Vietnam, from Halong Bay to the mountain regions.

Airlines on this route

Four carriers fly BKK-HAN: Thai Airways and Vietnam Airlines on the full-service side, with Thai AirAsia and VietJet Air on the low-cost end. The full-service carriers include baggage and a fuller cabin; the low-cost carriers sell baggage and extras separately while pricing the base seat low. On a route this short, comparing the all-in cost once baggage is added is the fair way to weigh a low-cost fare against a full-service one.

THB fares

BKK-HAN fares stay competitive given the frequency, rising around Lunar New Year, the year-end holidays and the Thai school breaks. For those peaks, six to ten weeks of lead time is sensible. Outside them, the low-cost carriers’ early fares are the cheapest, and three to six weeks usually finds a good THB price. Mid-week departures tend to be softer than weekends.

About Hanoi

Hanoi is Vietnam’s capital, an older and more measured city than Ho Chi Minh City, built around lakes and a dense, atmospheric old quarter with French-era boulevards alongside. It has a strong food culture and a slower, more traditional feel. For travellers from Bangkok, Hanoi is both a destination in its own right and the natural starting point for northern Vietnam — Halong Bay, Ninh Binh and the mountain provinces are all reached from here. The cooler months are the most comfortable for the climate.
