I can't remember when that TATL piece of the JV is over, I though something like 2021 but I could easily be off by several years, but AZ will almost certainly be out totally when it's up as they've already left the EU piece of their JV with AF/KL.
Although AZ is so messed up right now, virtually anything is in play with them...EY feeder slave, dissolved, back with AF/KL, and several others.
