Travel Essentials
SEA: PDT · PHX: MST
When it's 6:00 PM in Seattle, it's 6:00 PM in Phoenix.
Link Light Rail runs from downtown Seattle (Westlake station) to the airport in 38 minutes ($3.50 peak). Trains run every 6–12 minutes during peak hours from 5am to 1am. Ride-shares run $30–50 from downtown; SR-99 and I-5 can be heavily congested southbound during afternoon rush (3–7pm).
Sound Transit 574 express bus serves Tacoma ($2.50–4). Sounder commuter rail connects Tacoma to the airport area via a shuttle.
PHX Sky Train (free, 24h) connects T3 and T4 to the 44th Street/Washington light rail station in 5 minutes. Valley Metro Rail reaches downtown Phoenix in 20 minutes ($2). Uber and Lyft pick up at Ground Transportation on the lower level; follow signs. Taxis are metered; downtown Phoenix costs $20–30.Rental car agencies are consolidated in the Rental Car Center; the Sky Train connects there from both terminals without going to the street. For Scottsdale, Tempe, or Chandler, ride-hails are practical ($25–50). Express buses serve some suburban destinations.
Hot desert climate. Summers (June–September) are extreme. Daytime temperatures regularly exceed 43°C, occasionally reaching 48°C. Heat alone rarely cancels flights, but density altitude affects small aircraft performance. Monsoon season (July–mid-September) brings dramatic dust storms (haboob) that close the airport when they hit, plus intense flash-flooding thunderstorms that ground departures for 30–90 minutes.
Winters are exceptionally mild (10–22°C) with virtually no precipitation and near-constant sunshine. PHX has one of the lowest weather cancellation rates of any major US airport from November through April. Spring and fall are pleasant; late May and early June are hot and dry before monsoon arrives.
SEA–PHX Quick Facts
Frequently Asked Questions
Seattle to Phoenix: Pacific Northwest to the Desert Southwest
SEA-PHX is one of the busiest West Coast domestic corridors, with Alaska, Southwest, American, Delta, and Spirit together running 12 to 18 daily nonstops. Alaska Airlines holds the highest frequency given its Seattle hub position. Block time is two hours 30 minutes southbound. The 1,107-mile route is too long to drive practically (14 hours on I-5 to I-8) and too short for serious rail consideration. Phoenix Sky Harbor is a major Southwest Airlines hub and American hub; Seattle-Tacoma is Alaska's primary hub. The O&D market is large: Phoenix is the fifth-largest US city by population and draws sustained Pacific Northwest traffic for winter warmth, spring training baseball, and corporate relocations.
Operational Notes and Connections
Seattle weather (fog, low ceilings, and rain) causes more operational disruption on the SEA end than Phoenix, which has among the lowest weather delay rates in the country due to consistently clear skies and wide runways. Phoenix does experience convective afternoon thunderstorms from July through September during monsoon season, which can produce brief ground stops affecting late-afternoon arrivals from Seattle. Alaska's SEA hub banking structure means its PHX arrivals and departures align with international and domestic connections at Seattle. For Phoenix passengers connecting onward from SEA to Asia or Europe on Alaska, SEA-PHX operates in the inbound bank that feeds international departures.'\2
