Delta Connection flights (potentially single class cabin only) only take cash. United also did away with cash transactions onboard. Of course, if people stop buying things on board because they can't use cash the airlines will switch back.

Technically that's not Delta. That's run by a third party because it's not cost effective for Delta to operate small jets.

Technically it depends, but it's still Delta branded with Delta setting the policies. Endeavor Air is, for instance, wholly owned by Delta.

ah, yes, i don't usually buy stuff on a plane but that's a more prevelant example that i couldn't remember earlier.

Don't fly delta then.
