Hey, you can check out one travel report a pax on J class with JU did - it's here. Length of the flight is more or less the same so this is what you can expect. Also, as regards IFE, they hand out iPads loaded with videos etc. if you want them - there are no in-seat screens.

And yes, it's JU crew on BEG-AUH-MCT-AUH-BEG rotation, although they do change somewhere along the route, I'm guessing AUH. They also operate EY71/72 to BEG on behalf of EY, apart from their own daily (JU800).
