That's not the case with AA, though there needs to be award class availability to make a change. I had an off peak 40K London award booked last April that I moved to December without any cost.
If you're going to completely change airports, though, you'll need to redeposit the miles, pay for that, and try to find new availability. Don't think you'll be able to change the routing once you've started, so you'd need to make any changes before you start.
