What's the route? DL gives free wine and beer in coach on some routes. EC people also get free hard alcohol on some international routes. AFAIK movies are charged the same in EC as in coach, but I think there was a thread on this recently in the DL forum. I'm not aware of DL granting special privileges on board to elites in coach seats, and certainly not partner elites, although partner elites do get zone 1 boarding, some special lines for check in and security depending on the airport. DL elites get Have One On Us coupons for a free alcoholic beverage during OLCI but IIRC partner elites are not given this privilege. YMMV.
