When this route gets cheap.
The cheapest itinerary we are tracking makes one stop and takes about 18.5 hours outbound, on a 13-night trip — ticketed under Cathay Pacific, which on a connecting fare need not operate every leg. At $1,093 for 13,567 km each way, that works out to about $40 per 1,000 km flown. That is below the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 12 departure cities we track at a similar distance from Hanoi, this fare ranks 8th — 1.9× the $564 we hold from New York. That puts it in the cheaper half of the 30 routes of similar length we watch out of Dallas, where the middle fare is $1,168. We have 1 month of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage. Fare history here is still too short to name a cheap season. The best time to be in Hanoi: Oct–Nov · Mar–Apr.
We are still collecting this route's months — 1 month of cached prices so far, too few to chart.

Good to know
DFW → HAN, answered.
How far in advance should I book DFW → 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We do not publish a number for this, because we cannot measure it yet.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. Our guide Why flight prices change covers the levers we can measure.
Are there nonstop flights from Dallas to Hanoi?
The current cheapest fares involve a connection, ticketed under Cathay Pacific. 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.
