I have heard that a 3rd A380 and a 4th flight could be happening in 2016. EK19/EK20 swapping back to a 3 class seems like a great idea because I brings back the first class and the lost PAX would be made up by the 3rd A380 or the possible 4th Flight. A big announcment is going to happen in November for EK because it's the anniversary for the MAN service.
