The relationship between AF and AT is not that good, as AF sees with a very worried eye AT's successful drive into the Europe /Africa global travel notably with the creation of Air Senegal. This has been enough to put talks of AT joining Skyteam on hold indefinitely. To my knowledge, there is no agreement to admit Skyteam elites in the (excellent) AT lounge (just do not put anything private on the public access computers). This being said, this is Morocco. There are ways to get in.
