See the On-Time Performance section for the latest delay data at both airports. This shows departure and arrival reliability to help you plan.
Route data is updated regularly from official airline schedules. On-time performance data comes from recent airport delay snapshots.
Block time is 50 minutes to 1 hour 5 minutes for the 130-mile hop. Actual air time is often under 30 minutes. The flight barely reaches cruising altitude before beginning descent. You are airborne just long enough for the crew to run a drink service.
The drive on I-5 takes 2 hours 45 minutes to 3 hours 30 minutes depending on traffic. When you factor in airport time on both ends, door-to-door travel by air is often 3 to 4 hours. The flight makes sense mainly for connecting passengers routing through SEA, not for point-to-point travel. Amtrak Cascades runs the same corridor in about 3 hours 30 minutes with a city-center-to-city-center advantage.
Alaska Airlines operates 6 to 10 daily nonstops as part of its Seattle hub operation. Delta runs 3 to 5 daily departures connecting to its SEA focus city. United and American each offer 1 to 2 daily frequencies. Alaska uses E175 regional jets and occasionally Bombardier Q400 turboprops. Total daily nonstop departures can exceed 15 in each direction.
Amtrak Cascades runs 4 to 5 daily roundtrips between Seattle King Street Station and Portland Union Station. Travel time is 3 hours 30 minutes to 4 hours. The train runs along the Puget Sound waterfront south of Seattle with water views. Fares start around $29 one way. For city-center trips without checked luggage, the train is competitive with flying when you include airport time.
Seattle to Portland: Pacific Northwest Shuttle
SEA-PDX covers 130 miles in under an hour of flight time. Alaska Airlines dominates with 6 to 10 daily nonstops from its Seattle hub. Delta, United, and American add frequencies that push total daily departures above 15 in each direction. Most of this traffic is connecting. Passengers originating in cities without direct PDX service route through SEA to reach Portland. Point-to-point travelers between the two cities often prefer Amtrak Cascades or driving. The I-5 corridor drive takes under 3 hours without traffic. The route uses regional jet and turboprop equipment almost exclusively, with E175s being the most common aircraft type.
Ground Alternatives and Market Context
This is one of the shortest scheduled airline routes in the western United States. Amtrak Cascades offers 4 to 5 daily roundtrips between the two city centers, taking about 3.5 hours. FlixBus and BoltBus run express coaches at lower price points. The air route exists primarily because both Seattle and Portland are airline hubs or focus cities. Alaska, Delta, and others need to shuttle passengers between the two networks. Portland's airport (PDX) is consistently rated among the best in the US for passenger experience, with a single-terminal layout and MAX light rail service to downtown for $2.50. Seattle-Tacoma's Link light rail connects to downtown Seattle in about 40 minutes for $3.00.
