The flight and duty regulations are probably the most troublesome for us. We've spent a lot of time and effort trying to address them. I think the consultation on the regulations themselves was inadequate. They were advertised as a science-based approach. They were anything but. In fact, there was disagreement among the scientists and a very closed-minded approach, and it's costing industry money at a time when pilots are in short supply, as has been observed before.
That, for us, is the most troublesome regulation out there now.
