Cheap Flights to Las Vegas from Seattle

The Emerald City of Seattle is famous for the Space Needle, Pike Place Market and Twilight. The rainy, charming city of Seattle has Seatac, or the Seattle-Tacoma International Airport (SEA) to offer Washington travelers. The airport sits in the middle of the two cities near a major highway, making for ease of commute.

Flights from Seattle to Las Vegas are a dramatic shift in weather at a two and a half hour pace. This is one of the top three most popular routes recently traveled by passengers in recent years. The flights are offered by all major carriers and favor Alaska Airlines, where the airline is headquartered. Other often-used airlines include Delta, for which Sea-Tac acts as a hub, and budget airlines like Frontier and Spirit.

Sea-Tac hosts two satellite buildings — North and South — and four concourses with varying gate amounts. The SEA underground moves passengers between the concourses on the blue, green and yellow lines. To leave Sea-Tac, the Light Rail connects the Seattle airport with downtown and the university. Overseas travelers arrive at the Internaitonal Arrivals Facility (IAF) for processing after. The ambiance is airy and peaceful throughout the airport, and the dining and shopping are worth coming a bit earlier for check-in.
