When this route gets cheap.
The cheapest itinerary we are tracking makes one stop and takes about 5 hours outbound, on a 7-night trip — ticketed under Southwest, which on a connecting fare need not operate every leg. At $197 for 2,493 km each way, that works out to about $40 per 1,000 km flown. That is about the $41 per 1,000 km typical of short-haul fares here. Across the 6 departure cities we track at a similar distance from Dallas, this fare ranks 5th — 52% above the $130 from Washington. It is also the cheapest of the 7 routes of similar length we watch out of Boston. 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 Dallas: Mar–May · Oct–Nov.

Good to know
BOS → DFW, answered.
How far in advance should I book BOS → Dallas?
We do not publish a number for this, because we cannot measure it yet.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 Boston to Dallas?
The current cheapest fares involve a connection, ticketed under Southwest. 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.
