@kflyer2,
I've been trying to seek out more information regarding the sell/release agreement of 3 A330 aircraft of Srilankan Airlines. But unfortunately the details are still very sketchy. Therefore, I cannot confirm which 3 aircraft have been mentioned in the deal.
However, I strongly agree with your aricle published in the Airline Industry Review. It would be wiser for the airline to hang on to 4R-ALD, as it has a later MSN number than the other 3.
