Sorry, I was not more clear. I do not know whose fault it is when a connecting flight comes in late and one does not have enough time to get to the next flight. My point is that it is not the fault of the passengers already on the flight. Why should all of those people be delayed, for one?

Second point is a correction of closing the doors early. If that is the new rule, close the door 5 minutes before backing out of the gate, then that is THE time. One showing up 4 minutes before gate departure is LATE,not just in time.

If it were me I would be very upset having missed my connection, however as stated before, that is not good enough (selfish) to condemn others to be late on my account.

The statement that it does not matter when the plane leaves, but when it gets there has two flaws. First, if one does not care when the plane leaves, then why do we have this thread? Let the plane leave 50 minutes early and still say that. Secondly, it is convenient to say but the later the flight leaves, the more likely it will be late (can we agree on that?)
