Getting to LAX
FlyAway bus runs from Van Nuys and Union Station ($9.75, 30–50 min depending on traffic). LA Metro C Line connects to Aviation/LAX station; a free shuttle covers the last mile to terminals. Ride-shares cost $20–50 from downtown. Long-term parking lots A/B are walkable; remote Lot E requires a shuttle.
Getting from SEA
Link Light Rail from the airport station (inside the terminal) to downtown Seattle takes 38 minutes ($3.50). No transfers needed; trains run 5am to 1am daily.Taxis and ride-shares to downtown cost $35–55. For Bellevue and Eastside destinations (across Lake Washington), ride-share is faster than Link. Car rentals are in the consolidated rental facility; take the free shuttle from baggage claim. Sound Transit buses serve Tacoma, Renton, and Federal Way.
Seattle Climate
Marine west coast climate. Winters are mild but persistently grey and rainy (3–9°C). Snow is rare at sea level but can occur December through February, causing significant disruptions when it does. The airport sits between Seattle and Tacoma in an area that receives more fog and low cloud than downtown Seattle.
Summers are famously pleasant (18–25°C) with low humidity and mostly clear skies, one of the best flying climates in the US from June through September. The wettest months are November through January.

Alaska Airlines departs from Terminal 6 at LAX and is the dominant carrier on this route. United operates from Tom Bradley International Terminal (TBIT) on some services. Southwest uses Terminals 1 and 2. At Seattle-Tacoma, Alaska arrives at the North Satellite or Concourse D depending on aircraft type.
LAX is consistently one of the most congested airports in the US. Morning banks from 07:00 to 09:00 are the heaviest traffic periods, and taxi-out times can run 20 to 40 minutes depending on runway configuration. SOCAL airspace flow control can add further delays. If you have a tight connection in Seattle, choose a flight later in the morning when LAX taxi queues thin out.
The Link Light Rail runs from SeaTac Airport Station directly to downtown Seattle in 38 minutes. Trains run every 6 to 15 minutes depending on the time of day. The fare is $3.25. It is consistently faster than a taxi or rideshare during peak hours when I-5 southbound into the city backs up.
Los Angeles to Seattle: Pacific Coast Shuttle
LAX–SEA is Alaska Airlines' flagship domestic corridor and one of the carrier's highest-frequency routes. Alaska, Southwest, United, Delta, and Spirit compete across roughly 175 weekly departures. Block time is 2 hours 40 minutes northbound. The route is a true coast corridor. No connecting hub options shorten it meaningfully, so nonstop service dominates. The passenger mix is a blend of business travelers between LA's entertainment industry and Seattle's tech sector, plus a heavy leisure segment drawn by the relative proximity of the two cities.
Alaska's Hub Position and Competitor Dynamics
Alaska holds over 50% of the nonstop capacity on this corridor, benefiting from its Seattle hub and strong LA presence built through the Virgin America acquisition. Southwest competes aggressively on price, particularly mid-week. The route sees consistent demand year-round with summer peaks tied to Seattle tourism and a secondary peak around January when tech conference season drives LA-to-Seattle business travel. SeaTac's ongoing expansion (Concourse D international gates, South Satellite renovation) has improved the airport's throughput, though the single light rail link remains the most efficient ground transport option.
