Alaska Airlines Flights from Portland to Chicago

Alaska Airlines on this route

Portland is a Alaska Airlines hub, so Alaska Airlines typically offers several daily departures on PDX–CHI, with nonstop service where demand supports it and connections through its other hubs otherwise. The nonstop flight time is about 3h 55m.

Fare classes available: Saver, Main, Premium Class, First Class. No change fees on Main and First fares; fare difference applies.

Recorded lows on PDX–CHI start at $376 one-way. That figure comes from cached search data and moves with demand, so treat it as a benchmark for what a good price looks like rather than a guaranteed fare.

Delta Air Lines and United Airlines both operate hubs at one end of this route, so nonstop or single-connection service is usually available, along with American Airlines, Southwest Airlines, and Alaska Airlines. Our agents can book any of them and compare fare classes side by side.

1,735 miles is a serious flight, roughly 3h 55m nonstop, and it is the range where premium economy or a domestic first-class seat can be worth asking about, particularly on midweek departures when upgrade fares drop.

When to fly

West Coast and Mountain departures spike over summer holidays and the December break; January (after New Year), late April, May, and September are usually the cheapest windows.

Midweek travel almost always beats weekends on price here. If your dates are flexible by a day or two, tell the agent; shifting a Friday departure to Thursday or a Sunday return to Monday is the single most reliable way to cut the fare.

For domestic travel, booking three to eight weeks ahead usually captures the best price. Inside two weeks, fares climb; more than four months out, airlines have not yet released their cheapest inventory.
