EDF flew already in February 2006 and this makes her the oldest A380 in the Emirates fleet.
That would not bring it up to par with addasih 's "F = 6". Like I stated earlier, 007 had a "second first flight" in May 2009 after conversion. It must have been completely overhauled to zero hours at that time, otherwise the whole "F = 6" does not make sense.
If F=6 makes sense will soon become clear, as EDG would be next. But she just received the Wildlife decals and not for a few weeks, I guess. So I wait a little more before subscribing to the theory.
