The Boston–Washington route
Boston–Washington is a short US hop (412 miles, BOS to IAD). Nonstop BOS–IAD is often on the schedule, about 1.5 hours airborne over 412 miles. Ground time and bags often decide whether a cheaper nearby airport is worth it.
For BOS–IAD we show about $89 on the low end and around $165 as a more typical one-way economy total, USD, last reviewed August 2026. A $89 one-way is a sale-shaped guide, not a fare you can screenshot and demand. Taxes, bags, and seats change what you pay on the seller site.
Search BOS to IAD on Azurovia, compare airline-direct and travel-site totals on the same flights, then finish with the seller. We do not ticket. Keep their confirmation for changes.
Distance and time BOS–IAD
Great-circle distance BOS–IAD 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.
BOS and IAD 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 BOS–IAD 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 Boston to Washington
Both ends are in the United States: Logan International (BOS) to Washington Dulles International (IAD). 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.
BOS is the only origin code we list in this metro. On arrival, DCA (Washington), BWI (Baltimore) can price differently from IAD. 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.
