Why is anyone surprised? He was flying on the 764 which is the oldest cabin of any wide body in the DL fleet. I just flew the 764 on DL836 in Y and the cabin was filthy just like in the video. The IFE barely worked, paneling was falling off the OH bins, and my seat was partially broken because the recline mechanism kept getting stuck in. I would avoid the 764 at all cost until the mods are done.
