How has that screwed the ops across the network for the past two weeks?
Ops are not screwed across the network, most flights are on-time or within 15-20 mins of being so, but AMS is having an impact, as well as other airports in the current network, at various times.
Emerald is also a new operation (and another which looks very much like the old one) who seem to be suffering similar delays at various times, although none of their a/c go anywhere AMS as far as I know.
These new operations still have to get their pax through the same security, ground handling, air traffic delays, weather etc, so very hard to establish/differentiate in those circumstances.
