Same issues here at PDX....although OLCI last night probably saved me from missing the flight to ORD. Biggest check-in lines I've ever seen. AS had operations people walking the lines to help, although not much they could do. Even in this day and age, hard to believe that these things continue to happen. Given that the only way to sell and assign seats on planes is electronic, backups need backups which need backups. UA learned that a few weeks ago.
Our flight left on time as the systems came back up probably around 9am.
