Do you get more miles for flying or is that an exclusion?

The First Part of your question - NO.

well doesn't that suck

It occasionally happens if you're rerouted involuntarily. The reason: with some airline computer systems it's easier to rebook you in the default fare class for your cabin rather than looking up your fare class and entering it. When an agent is trying to deal with a long line of angry pax from a cancelled flight, getting fare classes right is (correctly, IMHO) not his/her top priority. Of course, it's hard to plan for that - and not necessarily something you'd look forward to anyhow, unless getting miles is more important than getting to your destination on time. (This is the same reason people sometimes end up with class-of-service bonus when they're rerouted after upgrading a cheap ticket with an award or other upgrade credits.)

No, it doesn't. If you did, you could pay for one trip and fly for free for the rest of your life. Once all the airlines go out of business, what do you do then? Either that, or award tickets go up to 1,000,000 miles each.

As above. However, last week I had a delay of several hours on an international award ticket and NWA mailed me an unsolicitated apology and credited me 1k miles. I thought that was very nice.

I just got home from an award flight using Delta miles to Rome, connecting thru Paris.
We missed our flight from CDG to FCO because AF was late getting into Paris.
They did rebook us on the next flight out to FCO which happened to be on Alitalia in BE. But she must not have entered the right fare code on the new ticket, because when we got home both my wife and I got credit for the flight plus a 50% bonus posted to our Delta accounts.

So, it can happen but only on rare occasions and is always a mistake on someones part.

Also they lost our bags and we did not get them till noon the next in FCO.
Which is par for the course for AF from what I read here.
So I don't feel a bit guilty for getting the miles for the flight.

That's a bit melodramatic don't you think? The only way you could "fly free the rest of your life" is if the number of miles flown equated the number of miles redeemed for the flight. While an outlying situation may exist where you get 25,000 miles for flying a domestic route it's highly unlikely.

I don't really think it would make any difference, because the price of the awards could be adjusted to reflect this. Think of the price of the award as a 'net' price. In fact, if you book online, you get a 1,000 mile discount.

Not at all. The award flight is the reward for earning FF miles with an airline. You don't really expect that the airline should reward you with more FF miles just for redeeming miles earned previously?
