They look to have solved whatever problem was killing the operation every lunchtime through Schiphol on both lines of flying, from which they never recovered. I wondered if they were trying to get the daily checks done by KLC in AMS and they've moved that to the evenings instead when the aircraft have a couple of hours' turn between the last arrival into AMS and the final sector of the day back to base. I can't think what else would have been causing an issue.
