In response to the A380 queries, the first flight is still confirmed as Wed 1st September. Although a 'small snag,' is the delivery of the No: 2 airbridge which will service the upper deck. According to a very good source within the planning team, this isn't due to be delivered to the airport site until very, very late August (Best estimate at the moment!.)
To add to this, even though the 1st flight is the 1st of September, the 'inaugural' flight is, I believe, Saturday 4th September.
Emirates, together with MAG, have decided to invite the regions'/countries'/worlds' press to the 'inaugural' flight 3 days after the 1st flight so as to hopefully iron out any problems that may occur during the first 3 turnarounds and to hopefully have a few less hangar-on-ers around and about. we'll see.
