About the Chicago → Seattle route
Chicago to Seattle is one of those domestic routes that punches above its weight. At just over 3 hours in the air, it's not a grind — you'll barely finish a movie before you're touching down at SEA. Alaska Airlines runs this corridor like it owns it, and honestly, for Seattle flights, it kind of does. The route attracts a solid mix of tech workers commuting between two major hubs, Pacific Northwest outdoor obsessives, and people visiting family who relocated for the Amazon or Boeing jobs. It's a workhorse route, not a flashy one.
Why travel from Chicago to Seattle?
Seattle has a personality that Chicago travelers tend to either love immediately or need a second visit to fully appreciate. Pike Place Market is the obvious starting point — not because it's on every tourist list, but because it's genuinely good, especially early morning before the crowds show up. Capitol Hill has a coffee shop, record store, or bookshop for every mood. If you're into the outdoors, the Cascades are close enough for a day trip, and ferry rides to the islands are cheap and quietly spectacular. On the business side, Seattle is basically a second headquarters city for anyone in tech, aerospace, or logistics — so plenty of people on this flight are heading to meetings, not just mountains.

Practical tips for ORD → SEA
Summer in Seattle is legitimately great — dry, warm, and the city is at its best. Fall is underrated and cheaper. Avoid expecting Seattle rain to ruin a winter trip though; it's more of a persistent grey drizzle than actual downpours. At SEA, the Link Light Rail connects directly to downtown for around $3, which is the obvious move unless you're heading somewhere suburban. No visa drama for US domestic travel, obviously. One thing people miss: SEA has separate N and S concourses connected by train inside security, so give yourself a few extra minutes if you're connecting onward.
