Dumping the A321s is not such a fab idea and certainly not off the Cork-Heathrow services as the last few weeks can testify. Loads have been at 100 per cent for the four daily flights or at worst just literally a handful short.
Fine, if in the future they put on about two extra A320 flights to make up the shortfall. Thinking about it that would not be a bad idea - lot of new destinations could probably be started ex ORK!
How good a performer would a 772ER be off DUB's RW10/28 - could the aircraft's full capability be used? And what about the improved A340-300E that South African Airways use - is take off performance anyway better there?
