DAL4, a lot of them. A lot of 50's are coming off the leases. What will probably happen is that DAL will refuse to pay the current book on them, and if the carrier that is flying them wants to continue to use them, they will need to cover whatever DAL decides not to cover. It is another little way to try and get out of these DCI contracts.

I have the popcorn, and am getting ready for fireworks.

FWIW, the battle with Mesa is far from over. I see that coming to a head when the flying in CVG gets cut more.
