There's almost no room for (inbound) delays. It can be a long walk between the gates. AA is close to the end of A concourse which is quite a haul from the security points/centre of the airport. AS usually uses the D concourse which is at the other end of the terminal pretty much. If all goes right and you walk fast (I'd say mininum of 10 minutes?), you will make it. Otherwise there's a petty good chance you'll miss the connection (or AA will bump you if you're not boarded ontime).
