When this route gets cheap.
The cheapest itinerary we are tracking flies JetBlue nonstop and takes about 2 hours outbound, on a 2-night trip. We have 2 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 Washington: Apr–May · Sep–Oct.

Press a date to compare its fares
The median cached fare across this calendar is 23% lower than when tracking began on 8 Aug — $280 then versus $215 now, across 18 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 $112, on 15 Sep.
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
BOS → WAS, answered.
How far in advance should I book BOS → Washington?
We do not publish a number for this, because we cannot measure it yet.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 Washington?
Yes — the current board includes nonstop fares (JetBlue). The outbound leg runs around 2 hours.
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.
