A nonstop flight from Seattle to Las Vegas generally takes around 2 hours 30 minutes to 2 hours 55 minutes, although some of the quickest scheduled services can be closer to 2 hours 25 minutes. Flights depart from Seattle-Tacoma International Airport (SEA) and arrive at Harry Reid International Airport (LAS).

The direct route covers approximately 871 miles (1,401 km) between the two airports.

As of August 2026, Alaska Airlines, Delta Air Lines, Southwest Airlines and Frontier Airlines operate nonstop passenger services between Seattle and Las Vegas. American Airlines is scheduled to add direct SEA–LAS service from November 14, 2026.

Travelers can also choose connecting itineraries. Some of the shorter one-stop options take approximately 4 hours 17 minutes through Boise, 4 hours 26 minutes via Portland, or 4 hours 50 minutes through Santa Rosa.

Since the nonstop journey takes less than three hours on many schedules, flying directly will usually provide the shortest overall trip. A connection can add around two hours or more once the layover is included.

Direct flights connect Seattle-Tacoma International Airport (SEA) with Harry Reid International Airport (LAS).

The airport-to-airport distance is approximately 871 miles (1,401 km), and scheduled nonstop journeys generally take around two and a half to three hours.

Alaska Airlines, Delta Air Lines, Southwest Airlines and Frontier Airlines currently provide direct services on the route. Alaska and Delta offer several departures on many days, while Southwest and Frontier provide additional nonstop choices.

For travelers mainly concerned with reducing overall journey time, a nonstop flight is normally the most practical option because it eliminates the need to change aircraft or wait at another airport.

Passengers choosing an indirect journey may connect through Boise Airport (BOI) in Idaho.Some faster SEA–BOI–LAS itineraries take approximately 4 hours 17 minutes in
total, including a layover of around 55 minutes on selected schedules.

This makes Boise one of the shorter connecting options between Seattle and Las Vegas, although it still adds considerably more travel time than a nonstop service.

The complete duration depends on the connection available, so travelers should check the full itinerary rather than assuming every Boise routing will take the same amount of time.

Portland International Airport (PDX) is another possible transfer point for travelers flying from Seattle to Las Vegas.

Some quicker SEA–PDX–LAS schedules take approximately 4 hours 26 minutes, including about 1 hour 9 minutes between flights.

Travelers may also find connections through Charles M. Schulz–Sonoma County Airport (STS) in Santa Rosa. Selected SEA–STS–LAS journeys can take around 4 hours 50 minutes, including a relatively short connection.

Both routings provide alternatives when direct departure times are unsuitable, but they require significantly more time than flying straight to Las Vegas.

A number of additional one-stop itineraries are available beyond Boise, Portland and Santa Rosa.

Depending on the airline and departure date, transfer airports can include Ontario, Salt Lake City, Santa Ana, San Francisco, Oakland, San Jose, Sacramento, San Diego, Phoenix and Los Angeles.
