I just returned from Rio again. When transiting thru Sao Paulo I had the opportunity for lenghty chat some of the AC aircrew.
They told me that the 767-300ER is being replaced by the A340 on this 11 hour route effective July 5.
Among other things.........I'll get around to posting a trip report this week. It was an interesting flight from two different perspectives....I flew there in Y and returned in J.
