When this route gets cheap.
The cheapest itinerary we are tracking makes one stop and takes about 25 hours outbound, on a 11-night trip — ticketed under United, which on a connecting fare need not operate every leg. At $687 for 14,923 km each way, that works out to about $23 per 1,000 km flown. That is well under the $42 per 1,000 km that ultra-long-haul fares on this board typically run. Across the 13 departure cities we track at a similar distance from Ho Chi Minh City, this fare ranks 4th — 1.9× the $362 we hold from Los Angeles. That puts it in the cheaper half of the 27 routes of similar length we watch out of Houston, where the middle fare is $1,259. We have 3 months 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 Ho Chi Minh City: Dec–Mar.

The median cached fare across this calendar is 11% higher than when tracking began on 8 Aug — $812 then versus $899 now, across 13 recorded snapshots. This is a calendar-level trend, so an individual deal above can be lower. The lowest single day we have seen here is $639, on 25 Aug.
These are the only days we have a cached price for on this route so far — not the only days it flies. The search above covers any date.

Good to know
HOU → SGN, answered.
How far in advance should I book HOU → Ho Chi Minh City?
We do not publish a number for this, because we cannot measure it yet.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 Houston to Ho Chi Minh City?
The current cheapest fares involve a connection, ticketed under United. 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.
