I've noticed that with all the MTOW upgrades available, A330s with GE engines are still not labeled with an "X" (Unlike, say, RR-powered A330s today like CX's A330-343x)
I understand that they started to add "X" as a means to distinguish the MTOW from the original 215/217t A330. That being said, why isn't this applied on GE-powered A330s? Are the new MTOWs not available with GE engines? Anyone care to shed light on this?
