all in all it doesn't buy you much, you are correct. Sometimes they will actually put the skyteam elite luggage tags on for you. Though I agree with what other responders above noted about the upgrades. AZ's first priority is going to be AZ not skyteam.
Though my AF experiance today tells me they are in the same boat.
