Dont know about the EI A330's MT.
I must admit that I am surprised to hear that they will considering wet leasing in. (It has to be wet, because the Cabin and flight crew situation now is at breaking point at QR. The Cabin crew department could not at this point man an additional A330.
So, I am a bit sceptical about that particular option. But will try and find out more.
Agree with your comments on the KUL sectors. But, is there perhaps a landing rights / slot issue at KUL which would need to be addressed?
I heard that the latest A300 has just arrived. Can you confirm? Didn't see it when I came back from DXB Friday. Normally would be parked down at the Control Tower.
