Just a slight change to its schedule, the Emirates A380 on 1st september has been given an extended ground time for its first flight, presumably for promotional tours etc.
EK17 lands at 12:25, and EK18 usually departs at 14:10, but for 1st september, EK18 will depart at 15:20.
I think this recent schedule change puts to bed any rumours that the first A380 will be delayed by a week.
