Well, only a couple of months ago, the official line was that the process was supposed to be completed by the end of this month, so we are looking at another 2-month delay if they indeed manage to get the remaining 7 frames reconfigured by that time.

The strange thing is that, if they can do 7 B772s in just 2 months, there was really no reason for dragging out the process the way they did. At a rate of 4 aircraft per month, they could have finished the entire B772 fleet within half a year.
