Corrected entry: In his log entry at the beginning of the movie, Captain Sulu mentions that he has been commanding the Excelsior for three years on a mission in Beta Quadrant. In the next scene, as they walk into the briefing at Starfleet Command, McCoy asks where Sulu is. Kirk has to remind him that Sulu is now a captain, and on assignment. It seems odd that McCoy wouldn't have known that, or that he would have expected Sulu at a briefing taking place very far away from the location of Sulu's mission.

Correction: In any large organization not everyone knows where everyone else is at all time. Kirk's reminder may have been a way of saying that a captain is not always able to be where he would like to be. He may have orders to be elsewhere.
