Flights from Washington to Chicago: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Washington to Chicago 
Verified travelerFlew with Alaska Airlines-Aug 2026
Be prepared to have a very difficult time checking in if you are not technology savvy. I could not figure out how to check in. It made me scan with my phone to check in, but I couldn’t figure out how to do it and then an employer was there pushed buttons on the kiosk and printed up a boarding pass. Where did customer service go?! and then, we had to wait in a huge long long long line just to drop off the bag. Be certain you give yourself extra time for all of this chaos. Flying is getting worse and worse every time I fly.

Budget if you’re planning on shopping for meals or souvenirs at Sea-Tac, it’s not cheap.
