About this route
Seattle to Phoenix flights
Seattle to Phoenix is a major snowbird and sunshine escape route for Pacific Northwest residents. Alaska Airlines leads from its SEA hub, with Southwest and American providing competition. The route peaks in winter when Seattleites flee the gray skies for Arizona warmth, and reverses in summer when Phoenix residents escape triple-digit heat.
Seattle's low ceilings and rain rarely cause cancellations but can slow operations. Phoenix is one of the most weather-reliable airports in the country, though extreme summer heat can occasionally restrict departures. The seasonal timezone wrinkle — Arizona skipping daylight saving time — makes landing alerts helpful for avoiding pickup confusion.
