When this route gets cheap.
Fares bottom out in November around $218 and peak in February near $346, 59% dearer, across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 4.5 hours outbound, on a 7-night trip — ticketed under Vietnam Airlines, which on a connecting fare need not operate every leg. At $218 for 2,199 km each way, that works out to about $50 per 1,000 km flown. That is above the $41 per 1,000 km typical of short-haul fares here. Across the 5 departure cities we track at a similar distance from Hanoi, this fare ranks 3rd — 19% above the $183 from Kuala Lumpur. It is also the 3rd cheapest of the 6 routes of similar length we watch out of Singapore. The best time to be in Hanoi: Oct–Nov · Mar–Apr.

Good to know
SIN → HAN, answered.
Is $218 a good price for Singapore to Hanoi?
Only slightly. The seasonal median is around $245 round-trip and this fare is 11% 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 Singapore to Hanoi?
Across 5 months of cached-fare history, Nov 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 SIN → 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We do not publish a number for this, because we cannot measure it yet.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 5 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Singapore to Hanoi?
The current cheapest fares involve a connection, ticketed under Vietnam Airlines. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
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.
