Agreed. However, what I learn from this thread is that in LAX you have two TSA pre-check lines, one for elite and one for non elite. Not sure that makes any real difference but one may need to ensure that they go to the correct line.
Second. how you entered the program may have bearing on your ability to use the precheck facility i.e. I googled it and found on that Alaska Air page that those who were were opted in by the AS program and do not have a known traveler number cannot use pre-check on another airline. However as you said, once you the status showing on the BP, you are good to go.
