The weekend hours limitation has an impact well beyond the actual closure. It prevents aircraft being used on Saturday mornings on the increasingly popular LCY flights to many Mediterranean points, because departing after 0700 it is marginal to get back by 1230, in case of any delay and all the expense of diversion, so the whole rotation is not attempted. It also stops the high end sports charters that would suit ideally the mainstream football teams, etc, returning after the event on Saturday evening, and again the whole thing is lost to LCY both ways.
