You're only assuming that it's the need of many. When did it become your right to demand what sort of people you associate with yourself? Where did this rule come from? The airline industry most certainly hasn't been spreading this as fact, and as I said. Anyone who the airline books on it's scheduled service, can book it.
You're more than welcome to express your opinion. But I still find it very selfish. Perhaps you should book a flight where you can travel during the day, and you wouldn't need sleep. Why don't you change the way you travel? Does it not suit your needs?
It is a fact, whether widely known or little, that certain flights to certain destinations at certain times during certain days more often than not feature a large contingent of people travelling on business matters. Whether you or anyone else knows this or not does not change the fact that this is so. You may or may not know this, but some airlines already ban kids in certain cabin classes and there is a drive to do so on more airlines, which I applaud and support.
As for your other point, why should I book a flight during the day? The whole point of booking red eye flights is to make business travel more efficient, by minimising impact on the working day travel has. I can do little for my customers at 37,500 feet up in the air. There is no chance they will accept me telling them that I plan on taking a leisurely mid-morning flight to arrive just after lunch if their business closes 3 or so hours later. It will leave me next to no time to do what I am being paid for. So no, it does not and will not suit my needs.
