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 Seattle 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 Seattle to Las Vegas.

What is the typical flight duration from Seattle to Las Vegas?

The flight from Seattle to Las Vegas is about 870 miles and typically takes 2 hours 37 minutes nonstop. In the return direction it runs about 2 hours 45 minutes. The difference is under twenty minutes, so the outbound time is the one to quote.
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 Seattle to Las Vegas?

Nonstop flights from Seattle to Las Vegas are plentiful, with Alaska Airlines, Delta Air Lines, Southwest Airlines, and Frontier Airlines all currently scheduled on the route. Alaska leads with 64 weekly nonstop flights, Delta has 34, Southwest has 21, and Frontier has 9, all operating daily. Departures span from early morning to late evening, with times ranging from 6:25 AM to 9:29 PM.
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 comes from the fares quoted in the Priceline searches our route pages run for this route, for departures about 17 to 37 days out.

What are the ground transportation options in Las Vegas?

Taxis queue outside baggage claim at both terminals and run about $20 to $35 to most Strip hotels on a regulated metered fare, making them the fastest and most straightforward option. Uber and Lyft also serve the airport from designated pickup zones in the parking garages, typically costing $12 to $25 off-peak but surging sharply during major events. The RTC public bus is the cheapest way into the city at around $4 to $6 per ride, though it takes 30 to 60 minutes with transfers. Shared shuttles, hotel courtesy shuttles, limousines, and car rentals from the off-site Rent-A-Car Center round out the options, while the Las Vegas Monorail does not connect to the airport.

When is the cheapest time to fly from Seattle to Las Vegas?

Fares from Seattle to Las Vegas are lowest in late January, around $148. January is the cheapest month overall, averaging $154, followed by February ($173) and September ($188). June is the most expensive month at about $209, and fares peak in late December at about $220. The yearly average is $191. 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 Seattle to Las Vegas?

Book about 8 weeks before departure for the best fares from Seattle to Las Vegas, around $136. Booking in the final days before the flight costs about $211, $75 more. Booking six months ahead runs about $194. 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 Seattle to Las Vegas?

Yes — Frontier operates nonstop red-eye flights from Seattle to Las Vegas on Mondays and Fridays, departing at 9:29 PM and landing at 12:11 AM, arriving just after midnight in the early hours (not the next morning).
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 Seattle to Las Vegas?

Alaska Airlines, Delta Air Lines, Southwest Airlines, and Frontier Airlines currently operate nonstop service from Seattle to Las Vegas, with all four flying daily. Alaska is the most frequent with 64 weekly flights departing between 7:48 AM and 8:25 PM, followed by Delta with 34 weekly flights, Southwest with 21, and Frontier with 9. Typical fares are around $269 on Alaska, roughly $248 on Southwest, which is the low-fare leader on this route. Alaska is a oneworld member and Delta is SkyTeam, while Southwest and Frontier are not aligned with any global alliance.
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.

How reliable are on‑time arrivals on this route from Seattle to Las Vegas?

On the Seattle to Las Vegas route, Delta Air Lines is the most reliable carrier with an 87.2% on-time arrival rate and a 0.3% cancellation rate. Alaska Airlines ranks second with 73.2% on-time arrivals and 0.9% cancellations, followed by Southwest Airlines at 69.8% on-time and 0.3% cancellations, and Frontier Airlines at 66.7% on-time with a 2.0% cancellation rate. These figures reflect the share of flights landing within 15 minutes of schedule.
Methodology
On-time arrival and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; a flight counts as on time when it arrives within 15 minutes of schedule. 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 Seattle to Las Vegas?

Alaska Airlines operates the most flights on this route, using Boeing 737 family aircraft. Delta Air Lines flies Boeing 737-800s, Southwest Airlines uses Boeing 737-700s and Boeing 737 MAX 8s, and Frontier Airlines flies the Airbus A320 family.
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.

Which airline alliances serve flights from Seattle to Las Vegas?
