Let me get this right, so from what you wrote above A319 there is no cost savings for SAS to be running the whole SAIL operation.
It all makes perfect sense to me apart of one detail - why SAIL operation is still ongoing and 9 a/c are still Irish reg?
It would actually be a cost saving for SAS to cancel the whole CAE/SAIL deal?
Not to mention the future fine for CAE in Malaga...
