EZY rostering staff do an excellent job most of which is manual, I'd hold them up against any rostering team in any airline. They have managed the rapid expansion of a low cost airline for the past four years at rate rate that would make your head spin. We did under estimate the operational impact of the precision pairing using Carmen, a mistake others have made, but it's not as easy to anticipate that as you might think, however lessons has been learned. We did indeed test it and had been working with Carmen since last year before we brought it in for the operational trial in June.
JB007, AIMS have developed a pairing generator but we are not using it, we were working with Carmen before it was released.
Rostering is of course the end product of many factors which sit outside of the rostering group, like the schedule, utilisation policy, collective agreements etc. etc., and I have no doubt the human touch is here to stay for quite sometime.
