Cached-fare history: across 6 months, Apr is the cheapest for DEL → HAN. Best time to be there: Oct–Nov · Mar–Apr.
Fares bottom out in April around $339 and peak in December near $526 — a $187 spread across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 9.5 hours outbound, on a 20-night trip — ticketed under Singapore Airlines, which on a connecting fare need not operate every leg. At $339 for 3,001 km each way, that works out to about $56 per 1,000 km flown. That is above the $39 typical of medium-haul fares here. Across the 4 departure cities we track at a similar distance from Hanoi, this fare ranks 4th — 2.5× the $133 we hold from Seoul. For context, the middle fare among the 9 routes of similar length we watch out of Delhi is $308.

DEL → HAN, answered.
Is $339 a good price for Delhi to Hanoi?
Only slightly. The seasonal median is around $375 round-trip and this fare is 10% under it, about $36. 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 Delhi to Hanoi?
Across 6 months of cached-fare history, Apr 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 DEL → 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We do not publish a number for this, because we cannot measure it yet.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, Apr comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Delhi to Hanoi?
The current cheapest fares involve a connection, ticketed under Singapore Airlines. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). 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.
