Travel Essentials
SEA: PDT · LAX: PDT
When it's 6:00 PM in Seattle, it's 6:00 PM in Los Angeles.
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.
LAX has no direct rail link to downtown. The closest option is the free LAX Shuttle G to the Metro C Line station at Aviation/Century Blvd (fare $1.75 to Union Station, 40–50 min). Taxis use a meter; expect $35–55 to downtown and $30–45 to Santa Monica. Ride-shares cost $20–45 depending on destination and surge pricing.Rental car facilities are a short shuttle ride from terminals. FlyAway buses run to Union Station, Van Nuys, Hollywood, and Westwood ($9.75–11.25). For LAX Connect (the new people mover to Inglewood), check if it has opened at time of travel.
Mediterranean climate. Summers are warm and dry (24–30°C) with low humidity and almost no rain. Winters are mild (10–18°C) with occasional rain from November through March. Fog ("June Gloom") is common from late May through July, blanketing mornings until noon and causing departure delays.
Santa Ana winds occur in fall and spring, sometimes grounding departures briefly. Heat waves in September–October can push temperatures above 38°C inland, though LAX itself stays cooler near the coast.
SEA–LAX Quick Facts
Frequently Asked Questions
Seattle to Los Angeles: Pacific Coast's Highest-Volume Corridor
SEA–LAX is the southbound leg of Alaska's flagship domestic route and among the highest-frequency corridors on the West Coast. Alaska, Southwest, United, Delta, and Spirit compete across roughly 175 weekly departures. Block time southbound runs 2 hours 50 minutes. The corridor carries a diverse passenger mix: tech workers commuting between Seattle's Amazon and Microsoft campuses and LA's entertainment studios, leisure travelers, and students moving between Seattle's universities and Southern California schools.
Carrier Positioning and Fare Dynamics
Alaska's dominance reflects its dual-hub structure at Seattle and the acquisition of Virgin America's LAX position. Southwest's strong LAX presence and point-to-point model keeps base fares competitive on the corridor. Spirit serves the price-sensitive end of the market from Terminal 1 or the new West Gates. The route sees consistent demand year-round with no pronounced seasonal low, making deeply discounted fares less common than on leisure-heavy corridors like LAX–LAS. LAX's ongoing terminal renovation and the Automated People Mover project (opening 2024-2025) are changing terminal transit patterns; verify ground transport options on the day of travel.
