Flights Bangkok to Hanoi (BKK-HAN): Airlines, THB Fares

Airlines & baggage

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.

Monthly market-low pattern (THB)

Fare trends

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.

Seasonality & best time to book

Bangkok–Hanoi fares move with demand. The cheapest windows fall outside school holidays, Songkran and New Year; book 4–8 weeks ahead for normal dates.

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.
