I flew DL MD-11s from ATL to BRU and from BRU to ATL in June of 2000.
All I can say is that they aren't the most comfortable plane out there, but it's still flying! The layout is 2-5-2, so make sure that you have something other than the middle of the middle. The seats are pretty uncomfortable and there is nothing special like PTVs. I find Delta's service to be either good, or almost nonexistant (i.e. the flight attendants disappear), but never rude. The food seems fine to me on longhaul flights. There will definitely be one movie, maybe even two, but I don't think that there is enough time for a third, at least on the flight to CDG. Just enjoy it though because this might be one of your last flights on an MD-11! Delta will be getting rid of most if not all of them by next June I believe.
