What amuses me is that the airport has known about the operating hours issue almost from the beginning. The airlines knew before they started operating there. They knew what they were getting into and then decide, let us just ignore the restrictions when it suits.
So, why shouldn't residents object when the airport and airlines know the rules?
If the airlines don't like the rules, use Bfs! You cannot say that BA and EI were not aware of the rules before they decided to use Bhd. Why did they not take that into account? Unless, of course, they think they can just ignore them. One of the reasons why many people are getting fed up with big businesses.
