I did hear one line of thought that all RIN costs were put down under the 'transformation' bucket of money. Therefore not a direct cost to Flight Ops. That would at least explain some of the RIN lunacy. I can list 3 A330 Captains and 1 737 Captain straight up who had less than a dozen landings post training as F/Os on the A380 after being RIN'd off the 767- less than 6 months. I can think of another two who would have had only a year on the A380 as F/Os before retraining on the A330.
Such a waste.
Those now A330 Captains were also very fortunate that the A380 FO RIN process enabled them to get A330 Commands out of seniority. The lottery doesn't end at day 1!
