The Las Vegas–Washington route
Las Vegas to Washington is a coast-to-coast domestic pairing: about 2,061 miles between LAS and IAD. Nonstop LAS–IAD is often on the schedule, about 4.5 hours airborne over 2,061 miles. Red-eyes and Saturday-night stays change the total more than the map distance.
For LAS–IAD we show about $129 on the low end and around $210 as a more typical one-way economy total, USD, last reviewed August 2026. A $129 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.

Distance and time LAS–IAD
Great-circle distance LAS–IAD is about 2,061 miles. Block time on a nonstop is typically near 4.5 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.
Washington is about 3 hours ahead of Las Vegas on standard time (America/Los_Angeles vs America/New_York). Arrival clocks on IAD are local. That matters more on this pair than on a same-zone hop.
When LAS–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 Las Vegas to Washington
Both ends are in the United States: Harry Reid International (LAS) 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.
LAS 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.
