I flew Delta to MNL via NRT a few months ago and the plane was old and terrible. Something from the 1970's... a community movie screen type display (just one for an entire section) with a few terrible movies didn't make a 20 hour flight go any quicker. They also overbooked the hell out of all legs of the flight, no empty seats in either direction and they made us disembark in NRT even though the second leg was on the same plane.
