Flight from Spokane to Chicago O'Hare Airport

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.
