Didn't this change when the flight numbers went over to the new BA logic in about 1978, round about when the "BeaLine" callsign was dropped. For many years, only Lufthansa and Canada 3000 operated on the North Atlantic with even numbers west and odd numbers East. So "evens go East" was almost completely flipped by the late 80s early 90s.
