Cheap Flights to Seattle

Alaska's home turf vs. Delta's hub — Seattle fares stay sharp year-round

Flight Deals to Seattle

Seattle-Tacoma International (SEA) is unusual: it's both Alaska Airlines' home base and a major Delta hub, and the two carriers compete head-to-head on nearly every route. That rivalry drives down fares across the West Coast and on transcon flights, while Southwest and Alaska keep intra-West prices low. For travelers heading to the Pacific Northwest, the Alaska-Delta battle is a reliable source of deals.

Best Time to Fly to Seattle

October through March (the rainy off-season) offers the cheapest fares. Avoid the gorgeous but pricey summer months of June through August.

Frequently Asked Questions

When is the cheapest time to fly to Seattle?

October through March is the cheapest window, when Pacific Northwest rain suppresses tourism and roundtrip fares from California drop to $90-140. Summer (June-August) is the most beautiful season to visit but also the most expensive, with fares often doubling.

Which airlines have the cheapest Seattle flights?

Alaska Airlines, with its hub at SEA, runs frequent sales and competitive fares, while Delta's competing hub keeps prices honest on overlapping routes. Southwest is strong on West Coast hops. The Alaska-Delta rivalry makes Seattle one of the better-value PNW destinations.

How far ahead should I book Seattle flights?

For off-season travel, booking 1-2 months ahead is usually enough thanks to steady competition. Summer trips should be booked 2-4 months out, since peak demand from June through August pushes fares up quickly once cheap inventory sells through.
