Last week I upgraded my wife and me from economy to business on a 380 flight from SYD to DXB in October.
SeatCounter showed I class = 0
Expertflyer showed I class = L (L = this class is closed however the waitlist is open, please contact the airline).
So I contacted EK where I was told there is no waitlist for upgrades, but I got the upgrades without problems.
Expertflyer still shows I = L on this flight.
