Flights from Boston (BOS) to Washington (WAS)
The Boston to Washington route covers roughly 400 miles and takes about 1h 30m nonstop. 4 airlines compete on it — JetBlue Airways, American Airlines, Delta Air Lines, United Airlines — which keeps fares moving and makes it worth comparing carriers rather than defaulting to the one you usually fly. We have seen one-way fares on this route start around $84.
Washington has the rare distinction of housing world-class museums that charge nothing at all. The Smithsonian alone accounts for a dozen of them, spread along a National Mall that also holds the monuments and the Capitol.
Three airports serve the metro area, which makes it one of the easiest US cities to find a cheap fare into — the trade-off is that Dulles and BWI are both a fair distance out.
