It's unfair to blame rostering or indeed crew control at the moment. The problem as I see it is 2 fold, first not enough pilots and second a really bad run of tech delays. In the last couple of days it has been a major challenge to keep the whole operation moving, let alone on time. Simple fact is you can't make one crew do the work of two, no matter who you have working in rostering. Those guys just have to deal with the problems on a daily basis so they need some slack. If you really want to blame somebody try the genius who told them they had enough crew to cover all the extra FRA's etc.
