Methodology: learn how we calculate these charts
The charts “When is the cheapest time to fly?”, “How far in advance should I book?”, “What's the cheapest day of the week to fly?” and “What do round-trip flights from Washington to Las Vegas cost?” are built from the prices Priceline customers actually paid for flights on this route over the past 12 months or more.
Where a route has too few bookings to fill every point in a chart, we borrow the shape of the curve from a group of routes with similar price behavior and fit it to the fares booked on this route.
Because past fares don’t reflect today’s market, we then adjust the historical prices for current conditions such as inflation and fuel costs, using the round-trip fares found in recent searches on this route.
The chart “When is the best time of day to fly?” is calculated directly from the fares found in recent searches, not from historical bookings.
Frequently Asked Questions
Everything you need to know about flying from Washington to Las Vegas.
What is the typical flight duration from Washington to Las Vegas?
The flight from Washington to Las Vegas covers about 2,080 miles. The typical nonstop outbound flight takes 5 hours 7 minutes, while the return leg to Washington is shorter at 4 hours 35 minutes — about 32 minutes quicker, thanks to prevailing tailwinds. That return direction is the faster of the two.
Methodology
Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.
Are there any direct flights from Washington to Las Vegas?
Yes, there are direct non-stop flights from Washington to Las Vegas, with United Airlines and Frontier Airlines flying from Dulles and Southwest Airlines and American Airlines flying from Reagan National. All four carriers operate daily, with United running twice a day (14 weekly flights) and the other three each running once a day. Southwest offers several departure times from Washington National, including morning and afternoon options.
Methodology
Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.
What are the ground transportation options in Las Vegas?
Getting from Harry Reid International to the Las Vegas Strip or downtown is quick and easy, with taxis and rideshares like Uber and Lyft taking just 10–15 minutes and costing $15–30. Public buses run on RTC routes 108, 109, and the Centennial Express for $1–3, though they take 30–60 minutes with stops. Shared shuttles cost $12–25 per person, private SUVs run $45–90, and rental cars are available at the off-airport Rent-A-Car Center with free shuttles. Rideshare and taxis are the most-used and fastest options, while the bus is the budget choice; there is no passenger rail or monorail connection from the airport.

When is the cheapest time to fly from Washington to Las Vegas?
Fares from Washington to Las Vegas are lowest in late August, around $282. August is the cheapest month overall, averaging $292, followed by January ($312) and July ($317). December is the most expensive month at about $374, and fares peak in late December at about $405. The yearly average is $330. Fares are adjusted to current market conditions.
Methodology
Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.
How far in advance should I book tickets from Washington to Las Vegas?
Book about 6 weeks before departure for the best fares from Washington to Las Vegas, around $258. Booking in the final days before the flight costs about $310, $52 more. Booking six months ahead runs about $357. Fares are adjusted to current market conditions.
Methodology
Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.
Are overnight (red‑eye) flights available from Washington to Las Vegas?
There are no nonstop red-eye flights from Washington to Las Vegas, but connecting overnight itineraries do operate, with the long red-eye leg departing Chicago Midway at 10:55 PM and landing in Las Vegas at 12:55 AM on Southwest, or departing Charlotte at 10:35 PM and landing at 12:31 AM on American. Both land just after midnight, in the early hours.
Methodology
Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.
Which airlines usually operate this route from Washington to Las Vegas?
United, Southwest, Frontier, and American all operate daily nonstop flights from Washington to Las Vegas. United flies from Dulles with 14 weekly departures, while Southwest and American fly from Reagan National with 7 weekly departures each, and Frontier also operates 7 weekly flights from Dulles. United is a Star Alliance member and American is part of oneworld, while Southwest and Frontier are not alliance members. No typical per-carrier fares are provided for these airlines.
Methodology
Airlines and weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.

Carriers are ranked by arrival on-time rate on this route, and the carrier list itself comes from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

What aircraft are typically used on flights from Washington to Las Vegas?
United flies the most on this route, using Boeing 737 family aircraft. American operates Boeing 737 MAX 8, Southwest uses Boeing 737-700s, and Frontier flies Airbus A320 family aircraft.
Methodology
Aircraft types come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.
