Common questions

Which airports have cheap flights to Boston?
We are currently tracking 182 fares into Boston from 38 departure airports, listed cheapest first above.
Is Boston the cheapest airport for this trip?
Not always. Cached fare feeds cover big hubs densely and secondary airports sparsely, so a cheaper nearby airport is often simply missing from a normal search rather than more expensive. Our reverse search prices a whole region's airports against each other to surface it.
