Yeah I was CASS approved after week 1. (I didnt even have Mymesaba access until week 3, due to something out of our class's control... don't know what that was).
I had a gate agent look it up for me right after week 1 and I was on the CASS website. I've used AA a few times now, was completely full flight and I was number 53 on the standby list, but was the only one who could jumpseat, so it does have it's perks.
