Cheap flights from Boston

BOS — Logan. Boston sells its own nonstops to most of the world, so the fares below are mostly direct and the drops are shallower and more frequent. Every price below is in USD, because that is the currency you'd be paying in.

Modelled route history built for this release — not a live fare feed. The method is real and the numbers are internally consistent; the ingestion that replaces them is Phase 0 of the build.

3 of these 12 routes hit a fare worth telling you about in the last 90 days.

Our bar is 40% under a route’s own 90-day median — not off a made-up “normal” price, and not off what the airline says it usually charges. The sharpest here was Lisbon at $336 against a usual $778, 57% under.

Read the chart: the dashed grey line is the route’s median, the dashed indigo line is our alert bar, and every dot is a day the fare spent under it. A route with no dots is a route that has not been worth watching — we would rather show you that than hide it. How the bar is set
