About a month ago I had a trip FRA-RUH-FRA on LH 744.
The FRA-RUH leg was on D-ABVU: no personal IFE, just the overhead screens. There were rather large IFE boxes under some seats, restricting legroom (take note of that!).
The return flight RUH-FRA was on D-ABTK: personal IFE and no boxes under the seats. It was a night flight, so I must admit I enjoyed the empty row more than the personal IFE!
