If you want DL operated flights, EF doesn't have access to award inventory. However, EF does show award inventory for certain partners such as AF class O (which is likely to be zero) and others. You need to search them individually or sometime on the partner's own websites, but the latter is likely to show award inventory only available to their own elites or using their own miles, not DL miles.
