I would not be so hasty.
Slottery at airports has been a huge hassle over the years and at the same time a plan economy kind of environment, which may be reasonable to some extent to avoid overloading airports but at the same time has taken a lot of flexibility out of air travel too.
If someone makes an effort to look into it and to see how it can be improved and where necessary amended, I'd give them a chance. At least some of what was written there does not sound too daft, particularly the part about booking and not using slots, which is a practice to keep competition away. And there is more.
It's not unknown that you can encounter times on airports where there is no traffic worth mentioning, yet the slottery tools claim that there is no more slot available today.... That kind of waste needs to be addressed. Doesn't really matter who does initiate the discussion, but it's good to see that it's finally open rather than being set in stone.
