Distance and time IAD–BOS
Great-circle distance IAD–BOS is about 412 miles. Block time on a nonstop is typically near 1.5 hours; wind, routing, and which runway you use still move the clock. Connections on the same city pair add layover time on top of that flying.
IAD and BOS typically share the same standard-time offset (America/New_York). Daylight saving can still split them for part of the year — check the local times on the itinerary, not a screenshot from last month.
When IAD–BOS has a nonstop, that is usually the cleanest product. One-stop options still appear — they are worth opening only if the USD total is materially lower after you count the extra ground time.
Airports for Washington to Boston
Both ends are in the United States: Washington Dulles International (IAD) to Logan International (BOS). This is not an international itinerary, so the usual domestic bag and ID rules apply at the seller. Alternate metro airports can still beat this pair on price.
Near Washington, also compare DCA (Washington), BWI (Baltimore). BOS is the arrival code we treat as primary for Boston. A cheaper nearby airport only wins if the transfer still fits your plan. Search with “include nearby airports” when you want those codes in one results list.
