Fortunately I had a long lay-over in SEA, but it would be a real hassle on a tight connection. AA has never been able to print the boarding pass for the third connection when it's on AS.
Unfortunately, this is a feature of many (if not most) codeshare agreements. Often, the computer system connections are not perfect -- even though AA and AS both use SABRE.
In addition, if the codeshare partner agents handle the flights, it can add additional complications. For 1 or 2 flights per day, AA agents are just NOT going to have the same knowledge as trained AS agents. That being said, the AA agents should have known to call AS ticketing in Seattle when they are confused. Obviously, they were too lazy to get on the phone!
