When this route gets cheap.
Fares on this route stay within about $19 across the 6 months we track — season matters less here than timing the drop. The cheapest itinerary we are tracking flies Thai AirAsia nonstop and takes about 2 hours outbound, on a 15-night trip. At $147 for 987 km each way, that works out to about $74 per 1,000 km flown. That is above the $41 per 1,000 km typical of short-haul fares here. Across the 3 departure cities we track at a similar distance from Hanoi, this fare ranks 2nd — 11% above the $133 from Hong Kong. The best time to be in Hanoi: Oct–Nov · Mar–Apr.

Good to know
BKK → HAN, answered.
Is $147 a good price for Bangkok to Hanoi?
Only slightly. The seasonal median is around $155 round-trip and this fare is 5% under it. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Bangkok to Hanoi?
Across 6 months of cached-fare history, Oct comes out cheapest on this route. The best months to actually be in Hanoi are Oct–Nov · Mar–Apr — when those overlap, that's your window.
How far in advance should I book BKK → Hanoi?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 6 months of cached fares, Oct comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Bangkok to Hanoi?
Yes — the current board includes nonstop fares (Thai AirAsia). The outbound leg runs around 2 hours.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 17 October). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
