Skipness, you can't conclude that there is no market in Shannon from the RYR statements that they weren't making a profit there. It seemed to be RYR policy to overserve Shannon, presumably for some strategic reason. 6 based aircraft was way OTT. I'm sure they could have made a nice profit from 3 at the time.
One unfortunate by-product of the RYR explosion at SNN was the annihilation of the weekly influx of German charters.
