Just a note that the A380 that I took from Seoul to Dubai on 19dec11 was supposed to have the WIFI.
They announced it just after takeoff, but I searched and couldn't find any network that I could sign in to. I asked the flight attendant, and he stated that WIFI was normally on this plane, but wasn't working for this flight. Bummer! That would have killed some time!! So I just watched several Kathy Griffin stand-up acts on my computer and laughed myself to sleep.....
