Yes, DL metal only (it's in Flight Application section of fare rules) so only EU destinations that are served non-stop by DL from US will be possible. Note that open-jaw bookings will still satisfy roundtrip booking requirement for award, so you can potentially return from a different EU airport than arrival and still get 148K roundtrip award level.
